Now that I'm wind again I've notice that when you melee with fan it still doesn't hit the 2 squares to the side of first tile.
Also with Sharigan, didn't really notice when I was uchiha because of no drain, it sometimes takes a few tries to turn off and on. As a fan user chakra drains quickly so I try to use it for a second then try to turn it off, but it usually stays on(or takes like 2-3 tries) and can sometimes be a bit hard to notice during a fight(chakra usually runs out before I notice).
Last thing, Inferno when caught in Dragon Flame and hit with Phoenix Fire, inferno stacks quite high and does a ton of damage. Orange caught me in one and did over 600 damage in that one combo.
