I don't see this whole argument of "If you get killed by the same person you just killed you deserve to die"
Which part of this makes sense, seriously, read it again slowly.
Fine, a lot of the time you kill them from a distance, you are too far to be blown up. Or you just killed a camper hear or see a nade drop and move away or throw it, fine.
But far too often you kill someone on your way to somewhere, i.e. they enter a building, you shoot them on your way out, boom, just as you get in range of the indicator.
Killing someone just outside of a grenade kill to be blown the second you step into it is not fun.
Bah i'm just not a fan at all of this whole life after death thing, if you are killed, you are dead, wait for respawn imo. Last stand at least requires some interaction from the player after they have been killed, the fact that the nade drop is automatic is just stupid, and requires no skill.
