Allied racials aren't even OP. Void elves get a blink? OP. (Forget that it has a 3 minute CD, still OP). Nightborne get 1% increased magic damage? OP. (Forget that most specs "high parses" are based on RNG procs so 1% doesn't really matter overall. Still OP.)
New racials always look insane on paper, but probably aren't in practice. Most of the increased % damage is so low that someone less geared than you can still out DPS you because pretty much every spec is proc dependant now. You can get 0 procs in a fight but, hey, at least you have the 1% increase right? The 1% damage reduction will probably save you 1/1000 times. Really OP if you ask me.
