Just something i see alot on other servers 5 hard parry = 1 ac if one handing a weapon, to make parry skill useful etc. because the perry mode isnt very good and this would help dex characters and make the skill not useless. could also add a fencing/swashbuckler class for this kind of build
also the soundtrack for the tavern music in DAI is amazing but not sure how viable this is {enchanter,sarah}exaples
Additing a new source of easily obtained AC would have to also come with overhauls to the existing mobs. That's a hell of a lot of work to shift a relatively stable meta to a new neutral position.
Duelist also fully realizes the fencing based class idea while having it's own crazy AC.
It also punishes tower shields quite heavily, I've seen it give AC too on other servers. And that was always a game of use tower shield at an early level and then switch to parry later. It would get pretty crazy if you combine tumble, and parry even though I agree the fact that parry is just absolute garbage is a little sad. But this solution without some hard requirement for dex would result in all the martial classes taking it for immense AC.
Parry could have been left out of the original game. To me, Parry feels like what Expertise is supposed to be, only without the 13 INT requirement.
That the Parry skill fails to pick up extra attacks in a "flurry" makes it wildly unpredictable in its usefulness for the steep price of your character not making attacks (unless you manage the +10 differential for a riposte).
