Frankly, to me this is long overdo. Manga and anime have made hay out of Chi tactics, and while I don't want Iron Fist shooting Goku-esque fireballs, some extra tricks besides a one-shot punch should be used.
Hopefully, Bru & Fraction remember that Rand can also use his Chi to boost his physical prowess to Peak Human levels, heal himself and others of injury, and be connected to K'Lun L'un. A few times he was able to absorb energy into more Chi but this was about as rare as Namor squiring ink. But baring these in mind, some new tricks can help.
