the reason is Stamina Regeneration + Rapier + Dexterity
the amount of iframes you can achieve is just frustrating to go against.
i know they made a change so there is a slight pause before stamina begins to regenerate. But instead of doing this, make it so stamina is constantly regenerating but at a very slow rate.
PVP should not be a game of dodging every 3 seconds to get iframes.
To compensate for the stamina regeneration being slowed down, remove the walking part that happens when you get attacked/ are attacking. this will make combat feel a lot more fast paced and less clunky too.
