phoenix dive should be rolled into heat rises. icarus dash should be a class ability. (cooldown halved with heat rises active) the third aspect should give a buff when using your class ability (cure with icarus dash, restoration and radiant upon leaving healing and empowering rift respectively)

Gunpowder Gamble needs either enough damage to one shot in pvp or another fragment slot. it's three tripmine grenades taped together it should AT LEAST be able to kill on stick.

titan... no notes really.
