Plasma Blast + Ferocity not supposed to work together ?

So Plasma Blast has a wind up time, and i was looking at supports for it and when looking at Ferocity (consumes a frenzy charge, +40% more skill speed when consuming a charge) and i thought it would be excellent for being my frenzy charge dump skill but it does not seem to work.

When using plasma blast, the frenzy charge is consumed as soon as i start charging, but the wind up time does not change.

is the wind up time not related to skill speed ? i thought it would be an obvious fit, and it consumes the charge before even shotting, but nothing seems to happen.

Ya I was thinking the same thing looks like Attack Speed is the only thing that effect Plasma Burst and Rapid Shots wind up.

Wondering if we ever got any answer to this question? Also, since you are technically loading the shot, does it count against reload speeds instead of skill or attack speed?
