Accessibility =/= Skill Ceiling.
The fact that performing certain inputs and hitting certain links in NRS titles is easier than in games like Street Fighter is a good thing.
A somewhat common argument I hear in MKX vs. SF4 debates essentially boils down to "SF4 is better because the execution barrier is higher." Now, I do not play SF4 (although I have tested it out), and therefore I hold no opinion with regards to which game is better between the two. That said, arguing that SF4 is better because of its absurd execution barriers is not only backwards, but also an out-and-out logical fallacy.
Having a lower barrier for basic execution is objectively good (Keep in mind that "barrier" and "ceiling" are two different things, i.e. MKX still has Instant Air Ground Pounds, Fireball Cancels, and 3 frame links).
So no, MKX isn't "scrubby." There is nothing "scrubby" about not having to break your fingers trying to get fireballs out consistently, or not having to pray to whatever gods you believe in that your dragon punch will come out.
This is why SFV is increasing the length of the input and combo windows over what they were in previous titles. They were finally smart enough to realize that requiring 1-frame links for everything was pretentious and esoteric. As such, I might just give SFV a real try.
