Thanks.
And yeah, feels dumb considering all the other things you have to keep in mind and the dps loss from using the wrong pas can't possibly be balanced out by a pp cost reduction on a single pa.

Yet another poorly designed skill in Sega's quest for making things diverse without regard for usefulness.

Quick Slash and Tech Arts JA Multi Bonus are a different matter, though, because both are good. Swiki says:
A normal attack, weapon action (including enhanced attack shoot), quick slash, quick shoot, and slash rise (slash fall) are considered to be a continuation of the combo.
Judgment that the combo is interrupted for step and style purge.

Good, cause I want to get used to use Quick Slash more often.
