My point of view on your subclasses.
[b]Titan[/b]: already has an AoE super (arc) and the solar sword super sounds a lot like the Hunter's Bladedancer class.
[b]Warlock[/b]: it's Sunsinger class is already a buff, even if it's just for him and he doesn't get a damage buff. But why would they give the Warlock 2 buff supers?
[b]Hunter[/b]: he already has a cloaking ability, even if it's just a perk in the Bladedancer class.
All and all, good ideas. But they're too similar to the previous subclasses.
