Well, see, you're falling into the same trap. You make a vague statement about having ways to deal with it and use that as an excuse to justify dismissing the criticism.
A couple of things to consider:
1) You could "deal with" SS attacks (or not having reliable SS attacks) in DOA5, as well. But apparently it's okay to subjectively dislike that system, but if you subjectively dislike the DOA6 system, it must be because "you can't deal with it."
2) I play Lisa. This new SS system is great for Lisa players. It favors me far more in most MUs than my opponent, and very rarely do I lose any matches due to SS abuse. Sure, I get popped with SSing sometimes. Everyone does. But it's hardly a bane on my performance, and more importantly, it doesn't shift Lisa's game-plan into something fundamentally stupid or unsatisfying to play. It does do that for other characters. It's like playing For Honor, where you just sit around terrified of attempting to initiate an offense. You can do it. You can deal with SSing no matter which character you pick. But is it dumb and detrimental to creating an engaging and satisfying gameplay experience? Yes.
3) In order to dismiss all proposed system retooling (ie: not character-specific tools for dealing with the system), you would have to state that any change to any of these traits would be inherently detrimental.
- All characters should have only one SS attack
- All SS attacks should be mids
- All SS attacks should have extremely generous hitbox/hurtbox ratios
- All SS attacks should be -15 on guard
- All SS attacks should grant a knockback that triggers wallsplats and danger zones
Thing is, if your claim is that "you can deal with SSing, so it's okay," you're saying that any system that can be dealt with is okay. Thus, in order to dismiss all possible alterations to the above, you would have to be arguing that you can't deal with any of those changes.
4) Imagine a hypothetical, where you had two SS attacks. The first functions just like the current SS attack, except that it's a high. The second is a mid, but instead of providing a wall splat knockback, it provides a pushback (either positive, negative, or neutral frames, can be any for the purposes of the thought experiment) with no wallsplat. Give each whatever frames on guard you deem most appropriate. Could you deal with this new system? Yes. Is it still highly evasive and useful as an anti-pressure tool that doesn't suffer the same cons people cite from DOA5? Yes.
It's far from perfect. You can debate the details of such a hastily concocted system and I may even agree with some of your critiques. But the point is that people don't even consider any potential perspectives. Instead, they fanatically dismiss all criticism by relegating it to "You can't deal with it and I can, hurrdurr" and if pressed, they default to "Well, it's better than DOA5," as if those systems are the only two options.
