Team would rather chase leona halfway across map because she appears to have less hp (1500) than the zed (900).
I cant really even get upset with most of them. At times they did make good choices. And its not like switching targets doesnt confuse the heck out of our team. Most of the time, you have to just keep blindly focusing the sub-optimal target or else.
I dont think assassins should be designed to one shot. They need to be built to go with poke comps. They can instantly do enough dmg to kill a poked target and then escape. Similar dmg lvls to bruisers, but with the escapes rather than tankyness to keep fighting. They need to be super elusive and hard to kill, I dont have a problem with that, they dont need to manhandle the game.
The level of dmg did to me after i bought qss was acceptable for an assassin. I had to back to fountain and we lost a tower. Thats enough reward for slippery zed. The fact that I had to spend 1300 gold to balance zed is fucking stupid.
