Elise,Blitz, Kha'zix, YI ( on occasion ), amumu, Shen, VI, akali
^Note: the only champion I personally have a problem with is Elise...
As I just finally got out of bronze and got into silver I still can not yet allow these champions to go on the enemy team..
For some reason at my current MMR no one seems to understand the concept/s of
( kiting, baiting, Tenacity, and initiating)
blitz problems = noob's just wont listen no matter how many times you tell them to stay BEHIND minions..
Shen problems = noobs don't realize that when you have 25% health and the enemy has 10% health as well a Shen Shield.. you RUN
