I'm a mythic raider that has played healer for the last couple of expansions. In Legion I'll likely reroll warlock and now I'm just starting to get over 700ilvl on my lock and bringing it to mythic farm. Currently playing destro, while I also plan to learn affliction soon.
The lock is a goblin currently and I do realize that's not the best race in terms of performance. I've been told troll is generally the best race but they also said the dps difference is very small. Purely from aesthetic view I'd like orc more, though. How big are these differences for mythic progression raiding and what would be the best pick (also looking towards Legion).
