My opinion Samurai just need flat potency increases for the time being. I would rather not see Seigan get buffed and I believe Square Enix agrees because they don't like skills on dps that encourage you to play reckless in exchange for a dps increase I think the minor increase it gives is fine as is lets say Shinten gets raised to 400 potency then I would want Seigan to be increased by 100 as well. I would rather that Third Eye mitigate more damage and feel more satisfying to use but not through Seigan usage and Im not really sure what I would waant for now. I do know that I want potency increases and I feel the potency needs to raise alot enough to be equal to Monk+Brotherhood
