1 shot by Rengar
He had Duskblade, leaped on top of me and I died. Literally 100% health to 0 health in less than a second, no exxageration.
I assumed it was an empowered Q with duskblade proc that killed me.
He did the same to our marksmen twice (using ult, we couldn't react fast enough).
Talon, LeBlanc, Fizz, Zed, other assassins all have their burst gated by a minimal 2 second damage proc.
