Self destruct passives should revive if they kill the champ that hit them last
I don't play these champs but it doesn't feel fair for some reason when I see Sion die after out playing the opposing team and dying any way

Current untargetable champs would need decaying health and be targetable like Sion to start
instead of having a CD on his passive, it is weaker the more it is used and stronger the longer it is not used, the speed, amount of blobs that drop, resistance scaling and blob health are the range.
