So with all the whining about melee being 'allegedly' overpowered I can't help but wonder -- What do you ranged people want?
Mages have more mobility than a monk, more CC than any non-warlock class, ice block that by all right should be a talent competing with double nova, respectable instant and on-the-move damage, spellsteal, polymorph, AND longest interrupt in the game.
A mage can kill any melee if he doesn't just stand on one spot and drool like a moron while wondering why he can't kill anything when after eating an interrupt he by his own choice doesn't cast anything for 20 seconds "BECAUSE HE'LL JUST INTERRUPT ME AGAIN!".
I won't list kit of every other ranged class as it's p. much common knowledge that druids (all specs) are way too mobile, hunters (when played well) are untouchable, ele shamans are great at kiting, and warlocks can easily tank 2 melees if they play smart. The only ranged I'd argue has genuine problems against melee is shadow priest; But again -- let him cast for 10 seconds and he'll destroy you, just like every other ranged.
This leads me to a conclusion that a lot of people that play ranged classes in wow are spoiled crybabies who's opinion on 'balanced gameplay' is when warriors and DKs are essentially free kills, and all a rogue can do is stun you for a bit then run away.
Ranged are fine. If you want tankiness, and more mobility, and to do more damage than a melee WHEN THAT MELEE IS WAILING ON YOU then I'm sorry but the problem isn't the game. The problem is you. I won't deny that certain melees (feral / WW / DH) are a bit overtuned for how mobile they are, but that's not a melee vs ranged problem. They kill other melees just as much as they kill wizards.
This whole melee vs ranged thing is stupid. In my opinion, the real problem is mobility / tankiness VS output. It's not tied to whether you're a melee or a ranged, but rather -- in a better designed system a class with as much ways to survive by various means as monk / mage / warlock / druid should also not be anywhere near top of the dps.
Holinka did say in pre-legion Q&A that they'll keep mobile classes from also being top dps. So far, only rogues were affected. Here's to hoping WW / MW / Mages / Druids / DH get some in 7.1.5 / 7.2, as well.
