In 1st edition Pathfinder, I loved playing Duelist and Swashbuckler characters. Part of what I liked about the prestige class and class was that attack roll vs attack of the parry and riposte mechanics felt more like real fencing than the roll attacks against AC score mechanics for other melee combat in the game.
The new Parry feats for Fighter treat parrying like adding a stiff layer of armor. It streamlines the combat, but it also lost the fencing feel and all the fun of the old parry and riposte mechanics.
It makes me worry that we won't get anything like the old parry and riposte mechanics with future archetypes or classes, which would be disappointing.
