There's still no drawback to it. With the Gentle Fist, the user injects chakra into each strike to attack the enemy's chakra points. At the very least, Chen should be required to maintain the effect with chakra which will mean he'll only be able to use it for a limited time. I think that would be a fair drawback.

That sounds like a plan. My thought process was he was using Ice Natured Chakra in each hit, but I am pretty cool with that too.
