No, it's not.That's an attack Vs a failed parry.
(B has a higher initiative, rolls first with a successful attack, A fails their parry)
No, it's not.
If you read the text that accompanies the image, it's an evasion combined with a counter-thrust. Both cuts and thrusts can be evaded, and doing so is a fundamental part of medieval and renaissance swordplay. You have to time it right, but you can do it. General evasions are something you tend to do as part of fighting, but you can also choose to sacrifice your attacks and jump back out of range (Volta or Evade).
For the record, I'm not just speaking theoretically, as I have been actively studying this stuff for almost 20 years.
If I correctly read what you're saying, you're counting "evasion" as part of parrying. Which I grant it often (typically?) is, but the official definition of "Parry" is "deflecting an incoming attack." And avoiding isn't deflecting. You can certainly evade a cut or thrust without having a weapon in hand. We do this at my school as a drill, just to teach people the importance of not just standing still. We take their weapons away and make them concentrate 100% on evasions.In which case it's a parry(B), attack(B), failed parry(A).
I know what you're saying but the maneuver is impossible without the weapon, so it's subsumed within the parry action.
6) Damage matters, as weapons are DANGEROUS. In the real world, a single blow from a dagger can kill you. Attrition based health mechanics (cough*Hit Points*cough) are useful from a gaming sense, but they're problematic for believability. And they can tend to lead to sloggy combats.

I grant that once you have a weapon in hand, it's very hard to separate the two, and thus they should probably be subsumed in a single "defend" action, but parrying and evading are technically different things.
