The point that you're missing, as well as the matches linked, is that this isn't a handful of free coin flips into advantage.
And neither is MKX, at least from the very top levels I see. Someone has to establish an advantage early, it just so happens in MKX that it can happen at a much faster rate because mobility is so good. This is why the guys who are really top (this is a small amount) are good at controlling the screen to where they can hit you out of movement.
Let alone, those games aren't anywhere on the level of MKX's level of fuckery and those games HAD defense options unlike this game.
SF2 Super Turbo, the first game I linked, has random dizzy, random damage, frame advantage as high as +9 on most normals and throws that are 1 frame with massive range and damage. To reversal when you are knocked down, you have a timing window that is often said to be from 1-3 frames to actually get your move out, which is almost completely impossible without doing a negative edge input to get around it. This game is still widely played today. Bottom line, "fuckery" is not keeping people from the game, just like it won't keep people from playing this game
The point is that in this game, it isn't just the top tier having access to top tier tools. Its like 95% of the roster with the ability to freely do this without consequence
This is the best way, often, to achieve the balance that so many of the troglodytes on the forum cry for. By spreading the wealth, you often get even lower characters who can absolutely crush you if you don't know what you're doing. Case in point:
Q in SF3: Third Strike is considered a not very good character, but in the hands of a player like Kuroda, the universal design options like extremely high damage and parry can help him overcome what would normally be massive defects in the character design. Suffice it to say, I think you will find that the majority of people prefer that the game let them rock on an even playing field rather than letting the top tier have their fun and only them.
You can't say top tier exclusive 50/50's in other FG's is the same as damn near everyone in this game being able to do the same exact thing.
Then what's the freaking problem? This, again, sounds like more of a defect in your thinking, rather than a legit flaw with the game. I'll be the first to admit that I don't play MKX because I don't like the delayed getup and I think it's largely ineffective and makes the midrange game a little too soul crushing, but I also am willing to say that this is largely my problem and that it doesn't really break the game. I just won't play it. Like I wish a lot of geeks on the forum would just not play it instead of having to listen to their design docs that are dripping with ignorance and too much glad-handling of MK9.
