Rough math suggests that the Samurai changes are a net nerf, actually

A redditor did the math, and it seems that the nerfs to Shoha, Zanshin, and the Setsugekkas will result in a net loss, especially in burst.

The top post of that thread sums it up exactly: much stronger in dungeons, especially with the AoE boost; slightly weaker in Extremes and Savage.

The savage tier pretty much has no DPS checks so I'm not sure if it really matters and I'm sure they'll buff it eventually. In the meantime I will have fun trying out Tsubame spam SAM.

This is the Way.

This seems to contradict what info I can find from the Balance, which mentions a rough gain of 1% damage on the 2.14s set and 0.8% damage on the 2.08s set (perfect loop).

It's also different from the first numbers we're seeing. SAM appears to be the third highest melee dps at the moment. Doesn't seems to be under performing at all.
