best part of the game is to prevent an ally from backing by constantly E him with 40% cdr and E lvl 5
precisely
as a trundle main its fun to counter many ults with the E

I love messing up a Karthus ult with it.
You missed a few

In my defense, I've only ever stopped Noct's ult once with pillar, it displaced him on his dash and was a complete accident.
i put tahm in there but forgot xerath and talia. but the others i had no idea :D

That thing is one of the best interrupts in the game. Long range, extremely short cast time. I remember completely screwing over a Fiddlesticks in ARAM once; never allowed him to ult at all.
