Quarterstaff Combo Mechanic

There are so many problems here. One thing is for sure, the Combo mechanic is either heavily bugged or it has esoteric rules that are not explained clearly at all.

1. Some quarterstaff strike skills just do not build Combo. I haven't tested every single skill, but so far I have found that Siphoning Strike does not generate Combo at all. Also, only the very first strike of Flicker Strike builds Combo. This is inconsistent since a single use of Whirling Assault is allowed to build Combo past the first hit.

2. Swapping weapon sets completely resets Combo. This especially hurts after the buff removing weapon swap delay.

The way I look at it is if the skill has multiple "strikes" to its activation, it builds combo. If it is only a single strike it does not. If flicker strike is building combo on one hit only, it is bugged one way or the other (either should generate no combo or should on every hit), or you have a combo generating support on your flickerstrike which would explain the single combo per use.
