One of my last games was against an entire premade consisting of:
Teemo
Twisted Fate
Ryze
Katarina
Vayne
All with Revive + Teleport.
I'm so glad they sucked balls, because those ganks were ridiculously scary.
Played as Jungle AP Xin that game, I went to start blue. I got there within about 45s, and when I walked into the bush their entire team was there..
Luckily AP Xin works much better than you'd think it does. 10/4/9 when they surrendered at ~27 mins
