I feel like the best thing Blizzard can possible do, rather than buff/nerf racials, is to just flat out not have them work in PvP at all. There you go. I've no idea how the Legion PvP system works with the talent system but it seems like the best solution for everyone to just not have them work at all.
But then we'll just move onto the next reason why one faction is performing worse than the other.
And yet i see the opposite, where most Alliance are either PvE geared or have barely any PvP gear. Maybe that's due to the faction number imbalance but you can't say one side has this problem and the other doesn't, because when it comes to the issue of gear, both sides experience it. Just like both sides experience defeatist attitude right off the bat before a game even plays itself out.This is something I've noticed a lot in bg's most alliance teams only have 1-3 people people that are there for gear most horde teams you see 70-80% of the team needs honor gear. And that's probably why horde gets wrecked so much on top of the other issues.
