These are interesting ideas but unlikely to happen. Scatter grenades just need to have a bigger and more consistent aoe on the explosives because direct hits pretty much always fail to do noticable damage. And when you pair this with how good we can fight in the air now compared to d1 they just aren't capable of being good because of how often we are in the air (which hurts consistency even more). If you didn't know, top tree void charging a scatter grenade actually makes them track targets, but it doesn't change just how crappy that grenade is.
