So it seems like everyone now agrees that we can expect a pretty bad factional unbalance. The question remains whether the staff wants to do something about it, and if so, when and what. I don't agree that "bribing" players to play alliance is a bad thing (also, it's not really bribing, since all it means is you're creating a counterbalance to the imbalanced racial perks). I also don't see how it's bad if players are being persuaded by it into rolling a class they otherwise wouldn't. It doesn't mean they will hate playing the game, it just means they've realized they're better off not swimming against the tides. As someone who had already played on TBC servers with factional unbalance, I can assure you that in case there will be no preemptive intervention implemented before launch, the following will happen (again, I'm talking from experience):
- Alliance players will literally be hunted by large groups of horde players while trying to quest at contested territories. A 2-minute quest will often take 30-40 minutes due to this. Many will get tired of all this and never even make it to 70, granting and additional spot for a horde player (self-accelerating effect).
- Even with a BG balance system that doesn't allow for a player count difference between teams higher than 1, horde will always have the upper hand due to that extra player as well as their far superior PvP racials. As a result of this, they will keep winning every single battle (the few horde players who managed to get in after waiting for way too long), get much better gear early on and thus become even harder to beat and more and more alliance players will get tired of this and quit.
- Alliance players will have a tough time finding groups for anything, be that a group quest, dungeon, raid or BG premade. Result is same as above, worse gear for pvp, less opportunities and more time consuming group building/waiting overall.
- Alliance AH will have much less to offer and it will be much harder to sell anything. Farmers will appear (although they will only be able to farm anything at the low-pop hours) so the supply might normalize, but the demand will still be too low, making it very hard to make gold and afford anything that horde players can obtain with ease.
All these things are guaranteed to happen, the question is whether staff wants to do something about it (and not too late) or it's fine with them.
I personally plan on playing Alliance, but if nothing happens to create balance, I feel forced to roll Horde instead, simply because I don't like the idea of missing out on a lot of PvE content due to dungeon/raid groups taking too long to put together.
