6.1 Changes:
Math checked using a hacked together rotation sheet, which just for full disclosure ends on a Midare entering a 9minute burst window with 65 Kenki and 1 Meditation banked. Dumping the potency of that 65 all at once at the end(a flat 702 potency) makes the number 8923.839.

The autocrit rotation is identical except it turns all that extra Kenki previously wasted spent on Kaiten into more scattered Shintens. This means that instead of ending with 65 Kenki banked, it has a full 100 Kenki banked. Dumping this full 100 Kenki potency at the end(a flat 1000 potency) makes the new number 8920.721.

If we ignore that Kenki potency dump at the end it's 8891.179 vs 8871.439 just for reference. We're basically at parity with before.

According to the balance. So Sam gets small nerf to dps, and doesn't synergise with dancer, sch, or dragoon anymore. Overall, these changes just make Sams perform worse in certain teams. Ironic since this is a team game.
