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

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.
