This is a long winded post, but I'm attempting to address all of the major issues that I feel contribute the most to the poor PvP experience on Warmane. I've played on this server since 2010, and honestly, I can say that each year, its gotten slightly worse. It makes sense that with time, the playerbase will get better gear and get better at the game, but a lot of the changes are misdirected and it's coming time that it's in the best interest of the gameplay experience to drop the idea of keeping the server 100% blizzlike. Minor changes to spellpower coefficients and talent tweaks would be inconsequential enough to still call the game blizzlike, when you consider how bugged every blizzlike private server truly is as a whole.
With the multiple non-blizzlike features already implemented on the servers, there isn't much sense in using this reasoning to prevent positive changes from improving the overall experience.
-----------------------------------------------------
Multiboxing
-----------------------------------------------------
The elephant in the room is multiboxing, and there have literally been hundreds of topics created as a result of it. I've offered the suggestion that /follow be removed from Battlegrounds and Wintergrasp to prevent multiboxing abuse and help to fight AFKing, and this change would perfectly fall in line with Blizzard's own changes, as this was done for battlegrounds in future expansions. There is virtually no negative to this change, but my post was removed from my recollection. This would fix multiboxing completely ruining Wintergrasp for everyone else, and prevent boxers from ruining BGs for people as well by not following objectives and camping for HKs. This doesn't address multiboxers completely ruining the gold market, but it would be a step in the right direction.

3.3.5a Balance
-----------------------------------------------------
The second biggest issue honestly lies in patch 3.3.5a itself. We all know what the strongest race/class combos are, and people tend to follow the path of least resistance. The diversity in PvP is absolutely abhorrent. It's at very minimum 60% plate wearers despite plates only being 30% of the class choices, not only because their gameplay mechanics are easy to grasp and are forgiving, but because the plate classes have access to shadowmourne. Patch 3.3.5b was a great step to improve gameplay diversity and experience for everyone, and I am positive that I'm not the only person who's completely sick and tired of facing nothing but holy paladins, arms warriors, and unholy DKs in 2v2. The gameplay for each class is fun and engaging in Wotlk, but the balancing really needs tweaking. 3.3.5a was never balanced with the intent of being played 10 years into the future, where everyone is already making characters entirely to cater to the meta, and everyone is nearly BiS. 3v3 has been dead since 2011ish from my experience, as I recall being able to easily queue at 2k MMR on the old Warsong server when it was 3.3.5, and it would be pretty simple to revive. There are no incentives to play it as it currently stands, as with the donation structure there's no real need to grind 2k for the shoulders or 2.2k for the t2 weapons, and the end of season rewards are worse than retails were by far. Challenger title is a title given to people that were like 1600-1800 rating, but it's give to only the top 10 or less teams here. Why bother playing 3s if you cant even get a chance at any of the titles, even the ones that were designed to be accessible? Mirror Blizzards title system (blizzlike), and offer unique rewards like mounts or toys, maybe increase the drop rate of scrolls, and more people will participate in 3s.
I think it would be wise to allow players with very high credentials to fill an application to help Warmane staff develop an improved 3.3.5b, and if possible, could make it only applicable to BG and arena instances so it doesn't have any effect whatsoever on the PvE experience. I also firmly believe that it's in the best interest for Shadowmourne's stats to be reduced to a 284 equivalent item whenever in an arena instance, as the statistics can back up the fact that it's almost a complete necessity to have in order to be competitive on the current bracket if you play a plate class, and it's an extreme challenge for all the comps that suffer vs warriors and DKs, like warlock comps. I have a 6.2k warrior and have gotten almost every class between 2k-2.4k, but I don't even play my warrior anymore, because there is no way for me to keep up with the pressure of a mirror with Shadowmourne, and it feels like a chore to even make it to 1800 since the entire bracket at every MMR is just as saturated with those teams.
-----------------------------------------------------
BG Brackets
-----------------------------------------------------
The third and final part of the puzzle is the BG bracket system. I understand the idea behind the changes, but its mostly been negative. It punishes players for gearing their characters and forces them to play against completely unfun teams every game. Since the new bracket change, I have not enjoyed a single BG on my 6350gs rogue. I have not won a single AV as alliance in probably 2 months. My last BG was a WSG with 4 healers and everyone else on their team was plate, and it wasn't even a premade. Hearing people say "make a new character on Blackrock and you get to have fun BGs" is really sad, because the whole point of an MMO is for you to progress your character and feel the power creep. Random BGs were far better on all 10 of my 80s between 5.8k-6.4k gs. Sometimes you faced premades and got corpse camped, sometimes half the enemy team was all new players you could 1v3 and feel like a god. It's easy for me to do 5 BGs in a row now and not have even gotten 100hks because nothing dies with all the BiS healers running around. Brackets should be reverted and if there is to be any split, try to make it a 2 part split between people below around 5.5k gs and above. It makes a lot more sense, and keeps BG diversity more interesting and entertaining.
I used to do some private server conceptual development in 2014 with 2 people who have/do work on your staff, and the server lead currently works at blizzard. When we were working on that server, these sorts of issues were already in discussion, and the problem has only compounded over the last 7 years. I think every single one of these individuals would agree with everything I have stated here, and I am very confident that your staff is more than capable of solving all these problems. It doesn't seem to me that the staff on Warmane is PvP focused, or really have the level of gameplay knowledge to make safe changes, so getting advice from the top 0.5% playerbase would be a really good way to gather good information that could then be sorted through and used to make good alterations to scaling/talents and bring the PvP experience back to life. It isn't a hit on your pride to look for external assistance. I hope that this post can generate some interesting discourse and that it isn't locked and removed, as I feel that it's a series of thoughts that I've had a decade to develop and experience from every angle, and as it currently sits, the situation here for PvP has been on a steady decline for years.
