RIDICULE must be a default ability.
ALL ABILITY OVERLAPPING REMOVED, for the one or two moves Kahn has in this category.
FASTER RECOVERY AND LONGER EFFECT TIME FOR RIDICULE TAUNT, or made the same as his priest buff (otherwise no one will ever use his iconic taunts).
FASTER START-UP ON FATAL BLOW, because without his spear specials equipped, it's very finicky and unreliable to combo into his FB (and damage scaling kills / balances FB combo use anyway).
AMPLIFY OPTION ADDED TO PROJECTILES -- Seeking Hammers should pop-up for juggles; forward hammer stuns (even if only like Cage's nut punch and non-combable); air hammer returns to Kahn's hands and pops up target for an additional air hit; spear holds target in place for a follow up (should not be usable outside of combo and only at close range, because of its height, making any comboing rather difficult anyway)
ADD UPWARD SHOULDER CHARGE SPECIAL, because the only allusion to this trademark move is as a blink-and-you'll-miss-it animation during his FB -- Amplifying this move could make Kahn impale opponent from mid-air using his spear (as he does in his FB)
CHANGE INPUT FOR GROUND SMASH ABILITY to down, down (2, 2) , from the awkward and illogical back, down (4, 2)
CHANGE INPUT FOR AIR HAMMER THROW to down, forward (2, 6), from the unwieldy back, forward (4, 6)
In the current roster, Kahn is the coolest character in that game, by far (IMO
)....HOWEVER, he has a lot of potential that feels like was slurred over in the hurry to get this game on shelves. To me, this opinion is proofed by the fact that the initial characters revealed (which Kahn was going to be the first of but wasn't ready at the time) seem so shallow now when compared to the later ones, esp. Skarlet, Baraka, Jade etc. I really hope they don't just get swept up in DLC profiteering, but that they revisit the exiting characters and improve them / build on their foundations... As many could use a fair bit of work to realise their potential.
