I kinda see where you are coming from, but at the same time it does reduce the amount of kicks per stupid tks. I've been kicked for lightning strikes from rushers, hunter killer drones for hitting walls next to team mates and people running into the turrets line of fire. I beleive they should fix somethings because now you can get any teammate care package you want by going lining underneath the drop spot, which is stupid.
Also fail blind nades in domination will not kill your teammates from capping the flags.
Just thinking out loud here, I 'think' it's a good tactic on 3arch's part to get more folks to try HC over Core and the rules are so folks can 'try-out' HC, and I'm pretty sure it's better to be kicked than to get in ear full in in game and then in the lobby post game. The sole problem I thought of when seeing the rules change is a-holes trolling (killing) their own team...but I don't know if that's a real problem or not.
