Backdooring Shacos: Toxic?

When a Shaco backdoors you, any attempt to intercept him is met with the same damn laugh and a poof of smoke as he runs away. Then when you're forced to deal with his teammates, he comes back and backstabs your turrets without minion support.

What a painintheass.

Counters? None, really. As I said before, if you divert to intercept him, you will not catch him. Chase him? Enjoy running into his pre-placed boxes. Call teammates? You just diverted way too much to deal with one backdoor, while the other 4 opponents death-push you or kill Baron. Homeguard? Recall takes too long. Teleport? Again, that laughing vanish.

"Shaco can't team fight! Of course he should backdoor!"

I thought Riot discouraged that kind of behavior... Then again, Shaco is toxic, so why should I expect someone to fight fair with him?

F%ck you, Shaco. You just cost me another series.
