I was main bard for 1 year, and i love it their movility, but now (for me at least) is incompatible with WM, anyway i'd like to leave my suggestions(choose one):

A. On WM, each proc of bloodletter reduce the recast of "Sidewinder" for 15s (the recast of bloodletter), of course that consumes the bloodletter, and if "Sidewinder" is ready, bloodletter still works like always, this suggestion is focused on the bloodletter issue, without change the core of WM and/or OP the class.

B. Simply made of Heavyshot an ability with 2.5s recast, that let us keep it the old rotation, and return our movility (the others skills keep their cast) and as "disadvantage" the heavyshot cast isn't affected for skillspeed. However this suggestion can make this skill OP, why? for example, without WM can we use HS and instantly use VB or WB like BL, even with WM, for that, maybe needs it lower their potency, and add it to empyreal arrow or sidewinder.

I choose B xD, but i think needs time to balance.
