Lets start with Moderator's definition (this thread : https://forum.warmane.com/showthread.php?t=483204) regarding blackrock lootbox system : "About the system, it's made to be just as grindy as gearing up in a full server with PvE activities. Don't expect it to go away if you pick playing linked to a progressive server. You're still free to create a character to play against Icecrown and not have to deal with the system."

And now what can we see here ?
1) about 4 teams from blackrock has Val'anyr's already , while entire Alliance at Onyxia struggling to get even 20 shards (90% of server population sits at 15 right now) , and for the Horde there is maybe 1-2 characters finally made it

2) entire blackrock has full BiS gear since they are "killing" Algalon , ofcourse , with getting 100% chance key forwarded to them (instead of trying to win it via /roll or DKP/EPGP bid from 24 more ppls , ofc) and full HM Ulduar , while there is maybe 3-4 guilds for the Alliance managed to clear entire HM , not even starting to complain about Algalon (49 Guilds from the entire Onyxia killed this boss , out of those 49 - 8 is Alliance xdxdxdxd)
How many guilds killed Yogg HM? ah wait , 20 from the entire Onyxia realm :) while entire blackrock is flexin' with full bis list including 239 ring , staff , polearm etc. (and yeah , items that you have to roll every week , competing against 24 ppl)

P.S. you grind Val'anyr to 1 person from the guild , while at Blackrock there is no any restrictions given , just saying xd

3) your (GM's) entire effort of trying to strict BLackrock guys to grind honour from BG's went to trash , because entire BG's filled with bots since there is no issue to get banned at Blackrock and to create another account , out of entire Blackrock population maybe 5-10% is bots

So , my question is , what's the point ? like literally , if you really intended to make the system this way - why mentioned above is happening ? Your system doesn't makes it "as grindy as it is" , it makes it x100 easier
and if you didn't - then maybe , just maybe , the same way of obtaining gear as it is at s8 should be returned to blackrock ? like , your so called "system" doesn't works anyways , so at least any one who plays PvP but has no intention to waste 8 hours a day on BGs (which basically worst content ever added to this game) would be able to just create a character at blackrock and play PvP

Or maybe , just maybe , you should at least reconsider your rating border for buying lootboxes at blackrock , because otherwise if it will be the same as it is now - next phase entire blackrock will flex with 272 cloaks and 2 DV / Solace's , while any Onyxia player who would like to try arenas will just eat **** .
