Melee classes aren't as strong early on, and so lot's of bad players whine that their 17 marauder is weak and cry for buffs/nerfs. When you get to level 40+ and still feel weak as melee class then you're just bad, simple as that. The closer to 50 the stronger the melee classes are. I too felt my Assassin was weak around level 20, but now, at 41 I can faceroll anyone except for lvl 50 tanks with good gear. I can only imagine it's gonna be even better at 50.
