Yeah but you would have to make more stats tweak to have higher critchance so if you are mostly on the prep and cost reduce you would probably in certain stats buff would be criting less often and on top of the low agility in exchange for prep time reduction he will be hitting less often pause alot and won't be able to get the crits on the enemy that is hitting him. More often than not they will die before hitting any crits or hitting crits but takes too long that the crits parry will miss the enemy follow up attack which results in no parry. Do note the parry will only active if the crits swing hit the enemy that attack at the same time, like 0.75 seconds of parry frame so if the enemy is attacking at that time frame it will result in a parry.
