out of curiosity does having it at 30 frames make it easier to do these actions or harder since id imagine it would be harder since u have less frames to work with and doing those things would be more "hardcore" if you are gonna call it that
A lot harder, to the point where it's not viable to do it at all. That's why some people worry about the game's speed. 30fps doesn't mean the game is slower, that's true, but if they want to retain links and stuff like that, it should be, otherwise it would not be practical to do them. They can either tone the combat down by removing those things/giving them bigger windows or keep them and make the game slower. Seeing how freaking big the parry window is in this game, they chose the first option in order to keep the combat fast.
There are also other things that relate to the framerate or lack of a hard lock-on that are not directly determined by those things, but are inevitable side-effects. Like have you noticed how freaking HUGE some of the hitboxes are in this game? Without the manual lock-on, you want to make sure the player will hit the enemy when they want to, so having those big ass hitboxes is a way to do it. The bigger focus on crowd control gameplay is also a side effect of not having the manual lock-on to keep it 1 on 1 all the time. The manual lock-on is also better for positioning with the enemy, without it we have this gigantic Enemy Step hitbox to make sure we'll get jump cancel when we want to jump cancel, but it also means we'll sometimes get it when we don't want it.
The visual fidelity of 60fps is also very important to get visual cues of when to press a button to perform a tight link, and I believe that when they talk about that "feel of 60fps" bullshit, that's what they're talking about, it will be as visually smooth as a 60fps game, but it won't have those 1 frame links and stuff like that because "the feel of 60fps" is not enough to make you perform links made for real 60fps.
That's why even though it is great that the PC version will be 60fps, it's not ideal and doesn't change it all that much, in the end it's still a game balanced around 30fps in its mechanics, just smoother. But that being said, it's Capcom we're talking about and it's quite possible that they WILL rebalance it for the PC version, with things like Turbo Mode and whatnot, so we'll see...
