Honey, everyone in the ladder has an Enigma. And yes, Barbarian is trash; a Smiter will crush him, as will a Charger. And a Zealot is a PvE character; it's pointless to use him in PvP. If an Elementalist at least has a chance to do some damage, then a pure physical attacker will lose in one go.
Lock, "evil rogue" is an evil rogue, and considering the role-playing possibilities in games, it's not just him.

Is being adequate a positive quality?
I've never understood people who think that way.

Yes, Wolf, being adequate is a mega-positive quality. Because being inadequate is negative. Why? Because a healer running into melee combat, an assassin who tanks and attacks from the front, a tank who sends a mage ahead because he's afraid for his own safety, a mage who decides not to cast Fireballs from behind the tanks, but to fight with a sword – these are all inadequate. There are interesting ideas for developing different classes, and I like them myself, but don't confuse them with being inadequate. Inadequate people are evil.
