Actually melee gets much better after you get to lv8-10 or so. It's still not perfect, but definitely an improvement over how clunky it was earlier last year. For instance my Marauder feels pretty damn good now, and the only time the controls feel truly off is when I'm targeting the smallest mobs (like the monkeys in Act II). Shadows are crazy good with Double Strike and fast weapons, they play very smoothly from what I've heard. I'm pretty much a melee guy in games like this, and so far I have no major qualms.
I'm kind of contemplating re-spec'ing my Templar. I had decided to go with a lightning based build, with minions. The minions were pretty boss in the early levels, but once I got to the prison they were dying super fast. Meanwhile my Lightning Strike does crazy damage, and I'm using Double Strike with a 1H axe...shit is OP as hell lol. So with all the damage I'm putting out, the minions seem like a waste of points.
