I got a weird idea here. I think it would be cool if I could sacrifice my melee or my grenade to be able to pick up another Fragment. Or maybe sacrifice both melee and grenade to be able to select a 3rd Aspect. I have a Stasis Warlock build, Frostpulse with Vesper of Radius, that I enjoy playing. I run around with the Winterbite smacking things and I enjoy it. But I never really use my melee and hardly use my grenade. So if I could trade my melee for another Fragment, that would be awesome. My other thing is that since I use Frostpulse, I have to choose between Glacial Harvest or Iceflare Bolts. If I could trade both melee and grenade to have all 3 of those Aspects, that would be awesome (IMO). Also, that 3rd Aspect would NOT give you the additional Fragments. Maybe it's weird and dumb, but I like it. I also had a Titan Stronghold build where having that extra Fragment would be nice, since I never used my melee either.
