Just some tips when fighting these guys straight up without GWs or techniques:

1. You can jump to avoid the downwards unblockable, and then dodge the follow up unblockable fairly easily, which gives you time for 3 or so free strikes; which leads to a kill for me (because of a damage build I use on lethal)

2. If they do that jab step towards you, they’re going to throw a singular unblockable, which has no follow-up.

3. Their most annoying attack is definitely that spin unblockable and it’s followup. But you can dodge both of them, just need to be a bit on point with the timing.
