You are wrong.
My melees are well-built, double or triple TRs with tons of epic gear (gathered by my wizard). They do well in quests. I don't need a caster or a healer to come along to succeed. My wizard is a single TR with ZERO epic gear, and he kills 5x as fast as my melee..
No melee can gather up 30 mobs and kill 25 of them with two button clicks... Oh AND have a self-healing aura going on at the same time.
