Teemo Shrooms.
I had 5200 health. about 40% MR. and these things were taking away 1/5 of my health. thats over 1k of damage. what on earth. he puts a billion of them too. i mean they should be more of an annoyance than a fucking damage. they slow you down which is what should be their role. few days ago I swear one teemo got like 15 kills of the mines alone late game. 15 KILLS.
