I could totally get behind this. It could even just be midrange to keep them still more oriented toward a smash mouth style. Maybe something similar to the cabal psions energy blast, but solar based. I'd also like to see the third hunter sub class be more team oriented. Maybe even as "simple" as a summon of sorts. Create a friendly mob I draw fire away from the team. Or maybe even a trap based sub class like I've seen mentioned around here. Something with less damage focus and more control focus. I'd love hunters to get a few slows and confuses mixed into their potential strategies. Warlocks might benefit from a similar team/support oriented treatment for their third subclass. Though I'm drawing a blank on ideas at the moment short of a simple heal/buff based sub class.
