For the longest time in this game I went without anyone ever saying "KS". I played my first bot game last week and heard it twice in a game from two different people. Now I've been hearing it almost every other day. The KS trend seems to be back in full swing (to my perception). Besides in a game like this, everyone needs gold, and chances are good everyone contributes to the kill in the first place.
Also in a game like this, if your WuKong is ksing every kill and builds to be a monster and wins the game because he ksd, does it matter all that much if he carried your w more?
