It’s mainly due to how people don’t like the strength of XF and how the game has a lot of mix ups that you can’t block on reaction (forcing you to have to react to the set up). Especially the up/down magneto stuff and the left/right stuff with assists. The second mix up is basically like how Seth can throw a fireball and then teleport on your wake up except it takes off half your life and you can’t use FA to escape the set up. Plus the opponent doesn’t have to be grounded for the mix up to work. Some of the characters like Dante have teleports that go behind you and track you so you’re forced to get crossed up no matter how far away you are from him as long as his projectile/assist can reach that far.
It’s just a game that on a basic sense is hard to get into because you deal with stuff like Hulk pressing on H and you lose characters. Then you get to people who know how to tick command grab and teleport assist pressure with Wesker and you hate that too. Then you get to playing people who can go up and down on you with sent drones and then even if you block that set you up into a 1 frame throw mix up that will put you in a combo any way. It’s not so much that it’s all random it’s just it’s not stuff you can make sense of if you play the game casually.
You have to play the game a lot to not get opened up everytime someone goes up and down or left right on you. It requires being able to see set ups for the mix ups before they occur and reacting to them with things like air throw, stand L/M/S normal or jumping out of the assist that they’re trying to left/right you with. SFIV Balrog sit on down back is pretty much a good way to get you killed in this game. You have to react offensively to defend yourself in this game and that’s part of why the throws in this game are one frame to give you an extra tool to deal with the extremely strong air based pressure.
Your down back in this game is like what Yipes says “UP BACK”. This blocks all high/low mix ups but doesn’t protect you from left/right or dash under mix ups since you’ll be blocking the wrong way if either happens. There’s no ground moves that can’t be air blocked like in other games so they make left/right mix ups prominent to blow up sitting on up back too long. You of course still have to worry about one frame air throws and command grabs as you’re up back/chicken blocking. Plus if the person hits you with a low attack after you fall from a chicken block you’ll be considered stand blocking and get hit.
The reason Chris G is so good at dealing with the “random” situations in this game specifically is because he knows when to block, when to air throw or stand normal punish a mix up and when to just space himself away before it gets started.
I would say the most “random” thing the game presents is characters still being able to TOD you too easily just by turning on XF2/3. You pretty much have to respect the character if you aren’t playing a character that can burn out their XF. Which means you will eventually get hit and have your team start to fall even though you were doing well.
It’s the same shit as how Sagat with Ultra and 2 meters in Vanilla SFIV could just come back on any DP he landed. In Marvel the problem is still there and basically on a worse scale since the game has no rounds and turning on XF2/3 with plenty of the game’s case can just hit you with that “random” DP FADC all your life crap.
