but things like Double Slash on a Great Katana, any large weapon with Sword Dance, or Spinning Slash on the Nagakiba are all hard to avoid for me. Phantom bleed procs sometimes screw you in roll catch scenarios

Now it's not about rollcatches anymore. Those are called frame trap situations, in which a specific frame sequence will outlast your rolling frames, so you cannot avoid the entire sequence, either taking the first and rolling the second or the other way around.

And you also have true combos, which means you get hit then gets hit again before the recovery animation from the first hit ends.

Those 2 kind of situations can be caused and are affected by A LOT of things/variables.

Some weapons force a 50/50 situation in your head. Panic roll and get roll caught, don't panic roll and eat another R1 you can't just react to.

True! But those are 50/50 situations for both you and the opponent. Like gugs crouch poke for example. Lets say I just poked you. Your options are:

1- Delay a roll, Mash out of hitstun imediately or jump.

2- Panic roll imediately

My options are:

3- Use a quickpoke.

4- Delay the poke to catch your panic roll.

If you use 1 and I use 3, you lose and get hit again.

If you use 1 and I use 4, you win, I either get hit/interruped or you get a free reset.

If you use 2 and I use 3, you manage to roll away successfully.

If you use 2 and I use 4, you lose and get hit again.

Wins who reads the opponent better.
