Sorry, haven't read through all the posts so this might already be stated. But, am I remembering right that you said the defiance buff takes place as you activate the power? If so, than potentially, a blaster could get their health lowered while teamed to a particularly low number (hey we die anyway it's the nature of the game, rez and eat a break free that should be enough) activate a nuke other high dmg power and before the animation is complete recieve a buff (both health and resist dmg or defense) from a team member. This would then give the blaster both the defiance boost and a nice chance of surviving the inevitable alpha strike from the surviving members. I might have to look into this.
PS. I'm not saying that as blasters we die more, sloppy players/risk takers die more. Players of all AT's die at some point and that is what I was getting at. I mean the dev's didn't put in the debt badge to make blasters feel that smelling dirt all day was important to the game, did they? (lol, I kid, I kid!)
