Rengar
Alright so I've started picking up rengar as he seems like a really fun champ but I can not seem to get his combo down for my life. For anyone who doesn't know the combo it's ult/youmoos, use fury q, jump on target and in midair you Tiamat bola and roar all at the same time and I can't do this after like 10 games as him. What should I do?
