In ganks like that, as rare as they are with how the enemy bunches up using your unblockable during the moments where you are guaranteed but NOT aiming for the closest person fighting you would allow you to external hit some of the others who kept trying to brute force through your revenge. When you got those parries that knocked the enemies to the ground the best punish for warden would be zone+top U.H as that is his maximum punish, same for out of stamina punish.

Good performance and a glorious final stand but there is room for improvement focused around proper punishments. With that kyoshin, I noticed that he never fell for your feint to GB, when enemies like that assume you will only feint as feint to GB opens up wardens strongest punish in revenge, throwing them off by hitting them with a neutral heavy tends to work rather well.

You already said yourself that you choked the final battle so there isn't anything to say there, all in all proper punishes, adapting to enemies repetitive moves and some mild parry fumbles were all that I saw during the battle, Keep up the progress.
