Please put Heat Rises on Prismatic 

If new Aspects do get added to Prismatic I think it would be the prime candidate because this would immediately open up a lot of fresh builds that aren't Buddy or Rift focused. It's the only real melee Aspect Warlock has and melee is by far the most lacking playstyle on Prismatic.

As for the competing Solar Aspects, Icarus Dash is cool and all but it's half as useful without Heat Rises and it does nothing for actual PvE builds. And Touch Aspects are generally being excluded apparently.

There's obviously the Lightning Surge Antisynergy with HR however 1) due to its low damage Lightning Surge is unlikely to kill something for HR anyway and 2) unequipping it in favor of Incinerator Snap leaves you with a higher damage melee - and one additional Aspect choice.

Or Heat Rises could also be expanded to not only refund melee on airborne kills but also grounded kills while the Heat Rises buff is active which would still require frequent airborne kills in order to keep the buff up. I'm sure it could use a bunch of other touch-ups like something for passive survivability in the air but that's another topic.
