Shen would be much easier to balance both for soloQ and competitive if he used mana

Stand United would be much easier to put in right place if Shen didn't have ability to out-pressure pretty much every mana-reliant champion in the game, simply because he won't ever run out of his resource. Right now the most realistic way to keep him from doing that is what Riot did - overnerfing him.

I know that ninjas are supposed to use energy, but I think forcing Shen to base as much as other champions do, periodically reliving that huge map pressure, would not only allow to put some power back into his kit, making him better suited for solo queue, but also make his competitive playstyle more interesting than "I'll just smack you, forcing you to smack me back, until you run out of mana, and than my team will start a fight you can't join", forcing more creative and exciting use of Stand United.

Right now Shen is "bad, but not completely terrible" due to buffs in 6.23, but we all know he will get Azired to the ground again after a round or two of LCS. Maybe giving him mana would be lesser evil: unlike Azir, who's playstyle is absolutely, completely terrible even in solo queue, Shen could be allowed to be a viable pick there without ruining experience for other players.

Also, I know you Shen mains have wet dreams about ;)

Thoughts?
