I dislike the idea of the Blood Elves getting so much more power as a single faction, not even talking about them as part of the Horde.
And the only reason I am okay with the Draenei appearing so powerful in this patch is because they've literally been shit on in every single appearance since their introduction. Even in Warlords of Draenor, when they're far more technologically superior than their MU counterparts, they still get smashed.
