I was trying a build and wanted to use my Glaive with a demolitionist perk. However the kills only granted me around 10% energy. I know some specials like GL's and Trace Rifles have lesser grenade regen rates but they are weapons you can get kills easier so I understand them having lesser regen rate. How ever glaive melees don't give you grenade regen and only the main blast does, this means the slowest special weapon in the game gives you the least regen. I don't want to believe this is intentional and I don't think it is, because fusion rifles (a weapon you can easily get a collat kill) grants 20% per kill. The fix is either make it work with the glaive melee kills or just bump up the regen rate on Glaives. I also found this video from 4 months ago and realized this matter didn't get much attraction which is probably why Bungie didn't realize this bug and not fixed it. I hope this time it will get noticed.
