I just picked up World of Warcraft for the first time (sue me for being late on the bandwagon, it isn't really my genre) and I was inspired by the monk's resource system. This idea was very spur of the moment and the general kit is plagarized from many of the League's other champions and WoW's monk class. However, I think there's a solid flow/theme to the kit regardless of how unoriginal it may be.
EDIT: They are currently disguised as drafts, but I'm tempted to have a trio of Kung Fu masters.
He currently lacks decent rank-up incentives on most of his skills. Although I'm not sure if that's a problem, given how fast paced it is.
Resource: Master Shang does not use mana and instead utilizes a unique secondary resource, Chi. Chi is required to cast Master Shang's W, E and R abilities, and is generated with his basic attacks. Master Shang can have up to 5 Chi, and it does not deplete passively.
With the exception of his ultimate, Master Shang's abilities do not have any costs related to them and their use is limited only by cooldowns. His ultimate uses a unique secondary resource, Chi. Master Shang generates Chi with his innate ability and can have up to 5.
Additionally, each of Master Shang's abilities are available at level 1 but can be ranked up normally up to a maximum of 6 ranks (4 on his ultimate).
Just some other random ability ideas.
You lot have expressed an interest in "brews", and while they may be appropriate in WoW where there's like 20 abilities to choose from - I think that (a) it conflicts with Gragas who has a drinking theme and (b) having only 1/5 abilities relate to drinking when the theme has nothing to do with drinking would seem wierd.
Also, as much as the spinning crane kick would be awesome - that's a little bit too much Garen/Wukong, isn't it?
