I'm sorry, but nobody ever should get hit by a 33F move, unless it low crushed someone.
You;d think so, but 33 frames are mere moments of a second. If every frame were even a tenth of a second long, I might agree, however when you are put into the heat of a match 33 frames is an instant, a flash in the pan.
At the end of the day, its the option that you still get hit with because despite its slow speed, its not something your mind is prepared to contend with.
At the end of the day, you jumped expecting Bane's command grab and ate that 32 frame charge on the chin. At the end of the day, you took that big hit because you were looking for the small one.
If we assumed a perfect world, no one would lose because no one would move from the start. However, humans are far from perfect. If given even a full second they still wouldn't find themselves capable of reacting.
There is no reason to get hit by any move above 16 frames, or so I heard in injustice. Yet every day we see people getting hit by 20 frame moves, by 24 frame mix-ups. Thats because people don't look for the wind-up, they guard expecting a hit.
I.E. they shoot where they believe the target will be, not where it is and not necessarily WHERE it will be. To place it into comparison, if Mileena's low was say... 16 frames, then the opponent would block low and their mind would have 17 more frames to both realize they shouldn't block low, sort through every other possible option, determine blocking high is correct, and then command the hands to do so. Fuzzy guarding is one thing, but then the mind considers another low is possible, a grab is possible, and so on. We cannot boil the human psyche down to the idea that they should not react to something because the mind does not come prepared with such things. Gamers rely on nothing short of conditioned responses and instinct, and anything that deviates from those responses (such as an overhead that is rarely used, or a less-than-optimal risk being taken) can't really be considered reactable.
The game runs at 60 fps. 33 frames is 0.51 seconds. The average human reaction time is 0.25, so just over double the average reaction and thats assume they know what they are seeing (which can take as much as another 0.1-0.2 seconds to register as a thought) and know how to react. The reason practice is so important is because it catalyses these efforts, making them streamlined and effective. You aren't going to be trained to deal with a 33f overhead any more than you would be to react to a 32 frame charge, and that charge was on a 30fps game.
You essentially had double the time and a much more obvious set of cues to react to (A sound plays, Bane makes big dramatic movements which draw attention to him) and STILL you'll see people eat that charge like a continental breakfast. Thats because humans aren't made to react on the spot. We're made to learn and adapt, so if theres something we haven't learned or adapted to then we aren't going to react as fast as you'd think.
I'd say for a completely original ideal to be reacted to on the spot and when other things are to be considered, your reaction drops somewhere in the neighborhood of an additional half second. And thats not including the natural inclination to react slower to attractive images and so on, thats just objectively speaking.
Unless you are specifically looking for the 33f overhead, you're trying to react to a 0.51 second move with about a 0.7 second reaction timer. Its not going to happen without you guessing beforehand and premeditating the block.
Lots of brain science. tl;dr, I'm basically saying its really not as outlandish as you think to get hit by a 33f move when you consider you're also looking for literally every other option first in your field of priority and are probably unaccustomed to considering it as an option.
