its correct, it explains clearly why hasn't been working, well its kinda deceiving if you ask me, having to add 1 frame to every single move displayed in the frame data execution wise.
I agree it can be missleading esp having played mk9.
To stay on topic, the biggest problem in mkx is the risk/reward balance of certain (offencive) buttons, strings and specials. I mean how can mileenas b1 at least not have a bit more recovery frames? The way it is now it involves almost no risk but leads into pressure or good damage (and thats only one example in this game).
TBH I don't even see how 50/50ies with one unsafe option are ok. Say you have to block a 50/50 for whatever reason, than this is going to happen:
you block low, oponents hits low -> no harm done
you block low, oponent hits high-> Oponent nets himself 35% dmg with one bar
you block high, oponent hits low -> Oponent nets himself 35% dmg with one bar
you block high, oponent hits high-> no harm done
Thats total 70% dmg with four options and about 17% on average. 17% reward for you trying to block. Same scenario with one unsafe option (assuming that you'll get out 35% as well) leads to 35% dmg in total and about 9% reward on average. Only with both options beeing unsafe risk and reward are even and on par with chars that have no 50/50ies.
