I'm relatively new, so please forgive me for asking, I thought the comment the game makes was YOIK, not yoink? And is that comment a result of "stealing" a teammate's kill while they are in the process of an assassination? Why is that frowned upon by a teammate if you are just trying to kill the opposition?
I'm not greedy about how many kills I get, I get my enjoyment from teamworking strategies that lead to a victory. I don't need to be a glory hound. Sometimes the sacrifices I make so that my teammate can double up on combined powerups creates more leverage to make another 6 kills that wouldn't happen if I didn't block and stall the opposition to help my teammate. I might be last in my team's standings, but sometimes the margin of the win is wide precisely because of that trade-off.
