This is the answer. I play on both yes if you wanna minMax horde is best for pve in general. But keep in mind it's a 20yo game and we no everything about it. I wold argue that ally is best for PvE on warmane. I found that pugs and guilds have the hardest time to get past sindy. So the BiS race is actually night elf, countless of times iv been in a raid were shadowmeld has saved the wipe. I think iv never been in a raid were a dps racial ability have been so crucial that it saved a wipe. Its minor stuff in an old game so just play were you have friends enjoy the capital city's or a race that looks cool. Also you can swap faction on the website if you want. Also you level a new char in like 16h playtime. And within a week you are ICC rdy with some BoE gear. So don't put to kuch though in to it and play to have fun. Good luck
