I know in the past the boards have sporadically had threads asking for ideas one fours abilities to make the most broken kit, but I'm thinking more, what two non-ultimate abilities you could combine into one to make something downright nighmarish.
The one that (somehow) immediately popped into my head was Warwick's Blood Scent and Kayn's Shadow Step. Think about it. You just survived a fight with you lane opponent, you go to back then suddenly BOOM, some werewolf SoB comes flying _through the wall_ and minces you.
Anyone else got some crazy combos?
