Sun shines, grass grows, birds fly, bad wizards whine about melee.
nothing new under the sun. Us melee (dk main) also live in fear of rogues and ferals, so it isnt melee vs wizard problem. It's a 'rogues are op' problem.
As for demon hunters, well; they're meant to be counter to mages. And yet every wizard besides sp and lock has a way to completely shut them down if you dont play like a spastic moron.
