As someone who plays a fair amount of Defender, I don't think War Machine is a problem. The degree to which it buffs your reload speed is obscene. I mean that literally. It looks like you are doing something to that shotgun that shouldn't be allowed in a T rated game. The problem with Defenders is the way their neutral talents are set up. Both of the two neutral columns have two of three talents that buff their super [i]and nothing else[/i]. Most other classes have at most only one or two talents that exclusively affect their supers, but the Defender has four. Of the remaining two, one is Iron Harvest, which only effects orb generation. They way to bring Defenders along, in my opinion, is to either combine talents like Bastion and Unbreakable so that something new can be added that improves the Defender's neutral game, or to add supplemental effects to certain talents toward that same end.
