What part of warding do you hate the most?
For me, it's when you go to one of the side brushes to ward it while playing as mid-lane, but that damn Lee Sin is already camping it before you get there and ults you into his teammate, resulting in a no-means-of-counterplay death.
It's at moments like that where I sometimes end up wishing for bad things to happen to the Lee Sin player. Really bad things.
