Alliance has paladins.
Alliance has dwarf priests with fear ward.
The major raiding guilds will be primarily Alliance, same as it was in vanilla, if people are as obsessed with min maxing as they were then. However, since no one is racing towards endgame and "world firsts" of old content that already have world firsts, this won't be something people really care about.
However, the raid guilds will still be mainly Alliance for one reason and one reason alone: Horde doesn't have blood elves.
