So I guess I would say that it's almost like putting too much power through a circuit. It can only hold so much until it blows. Their aura can restore enough to become fully restored and a bit more to grant more power towards some techniques (aura techniques, semblances, etc.) But, when overcharged, one's aura will begin to drain itself because of the excess aura, causing the target to lose control and drop.

Yes he does have to aim at the target and they only get replenished by being hit with the "aura-waves." And I'll tweak it a bit on the limitations.
