This is basically what im saying right now, Liu Kang when he touches you gets a blockstring into nearly 20% guaranteed chip and a full bar of meter off a jump in or low poke advantage, so you have to block the f213 and your other options are let go and standard breaker the f213, or Block breaker the f213 which both take 2 bars and your stamina is drained.
So he gets the string and a mixup which is mostly in his favour unless you have a 2 hitting armoured move, good fast reactions and can make a read on his parry every time. Meterless you cant armour his EX Roar (which is free after f213 from the meter gain) so it becomes a blockstring you can only low profile, but he can use low fireball in that situation to second guess your "best" option, so you are always on the back end of his wp mixup trying to make the best out of a shitty situation. Before they changed his WP you could punish it on block so he had to hitconfirm. Having his SF cancellable and + on block is fine i think, because its got a timer on it and its just a reskin of his DF fireball cancels, with a cool buff tied in. His zoning got improved but it was better in this variation already so allow it, its just now he gets meter and chip and a mixup for making you block, and he really can just throw it out whenever he has SF up because its such a good situation for him to condition you in.
