I'm not sure what just happened, but it was cool.

So I was facing an Irelia, she set up the 3 casters on the first wave and the first melee of the second wave to be 1 hit away from dying, and within less than a second, killed all 4 with Q, proc'd her passive, leveled up E, dropped it on my face, and killed me with AA Q AA Q AA ignite.

It was pretty fucking clean, gotta say, and I was so impressed that I wasn't even salty.
