Wouldn't it be more healthy if Zed had to live at least as long as his "death mark" requires in order to deal damage again?
Your opinions please! And remember we shall check whether you're Zed main or not ;-P
PS: Think of it as a discouragement to self-sacrifice tactics. Think of suicide-Sion tactics, too. And it is almost the same, only you take kills 1:1 instead of turrets. Feeding kills in LoL is not welcome anyway, on anyone.
