Rageblade a new core item on crit jhin?

Been playing a LOT of Jhin lately and have was recently told to get rageblade on him because apparently ImaQtpie did it.

After trying it (and having to get rid of it due to an hour long game making me get GA) Jhin can get up to 100% crit with well over 1.2k AD and 30% cdr (Typically I went ghostblade last item for the 40% cdr and bonus MS to go with celerity) this is not including gathering storm (if you take it) causing him to get even more ad as the game scales up.

Dunno if this has become a thing yet or not but if any of you want to, go try it in a game yourselves or practice tool. His numbers are insane
