**Solution** Cowardly third partying has to be stopped!

I like your idea because I feel like this game was designed more for aggression and not for passive play. However, the siphon ability rewards already great players while punishing the casuals... which make up a huge bulk of the player base. I will say that all your ideas shouldn't be in casuals, but it should definitely be in ranked. Hell, I would definitely play more ranked if it gave siphon on kills/wipes.
