I've been playing on a guardian now for a few weeks, I've only gotten to lv11 (cause I'm doing all the missions I can remember) but it's a very fun play.
Not only that, a while back I requested a "beam blasting" powerset, I'm not sure if you guys already had the same idea or whether you considered it when making Luminous assault, but I have to say, that is definitely good enough!
Just saying thanks, thats my feedback.
I'll probably have more feedback once I get to a higher level.
