Skillcap: what are the hardest classes to master.

[Amkô]

Every class is hard to master. There are warrios not able to handle their rage and stances, mages with bad positioning are easy targets and so on and so on

[Sham]

Mage, rogue and warlock

[Dusch]

I think hardest class to Play is Warlock!

You can ask Mr. Slippry!

[Irachkom]

Druid(Because its most hybrid class) and Warrior(because of become poorest PvP class in WoW)
Other classes are too ez
