After reading the patch notes, I guess I won't play SAM anymore
Aside from Third Eye extended duration, every change seems to homogenize Samurai to be just like any other DPS, or even worse.
There was no reason for Tenka Goken to be changed from a cone to circle, and nothing was changed to address what every SAM player suggested (merging shohas, ogi namikiri, guren merge with senei). If every job AoE is a circle, none of them will feel special or unique, you just go in the dungeon and do the same thing with a different attire.
Not only that, they made Wanderer's Minuet change into Pitch Perfect which was Literally what we were asking to change in Ikishoten / Ogi Namikiri. It's almost as if the devs don't share ideas or don't want to help each other.
As far as potency goes I can't say much about it. I know it'll probably do the same overall DPS but certainly does not feel nice to read your 990 potency skill (with kaiten) that could crit went to 600 but always crit.
