Sunbreaker needs some good exotics. Although immolation fists weren't used all that much by myself personally in Destiny 1, I think with how bungie has reintroduced some old exotics with new twists could prove to be beneficial to this and future returning exotics. For those that don't know what immolation fists did, it unlocked explosive pyre for free on sunbreaker so you didn't have to have the perk active in Destiny 1. I think this exotic is a really good chance to introduce a "doomfang" style armor that restores super energy during it's duration for hits. It obviously should keep the explosive pyre perk, but maybe get it's unhindered/unnerfed version it had in Destiny 1 where it was explosions galore. To clean this up as to not drag this out: Immolation fists: Grants ENHANCED explosive pyre to sunbreaker (including burning maul). Multi kills during super will restore super energy. Multi kills with solar abilities grant bonus super energy. This would open sunbreaker up to an extended duration on its super but make it a bit more unique. With burning maul, it would have a way to extend its duration while still putting out its glorious slams and spins. Let me know what you think.
I dunno.. bottom tree has Sunspots which extend super duration, so am exotic on top of that might be a bit broken. IMO
