No, even you mentioned he could track you with it, however he didn't know you fired a shot, that was instinct. he can track chi, and thus a person who has it, in its varying forms - but it wasn't used to track the shot.

Alphonse has a relatively fast movement speed, but as stated barely managed to dodge the arrow, had it been off-center to the left, he'd have gotten hit.

actually, in the initial T1 post Skally provided, it showed you can launch an attack and charge an ability at the same time, so long as the focus wasn't disrupted. you've shown no opposition to him using his passive and non-passive abilities(charging a shield, and slowly gleaning your abilities in chi/magic). which is no more convenient than Alphonse running headlong towards a tree just when you wanted to shoot.

that was actually my mistake, I misread your post about the clear shot.

we may need one, though I'm sure we can figure it out on your own. 

we still need one though, rules and all.
