I'd say I'm more disappointed than angry.
I feel like with Heavensward Bard just got slower and clunkier. I don't think any of the new abilities are particularly fun or interesting.
I also feel like SE didn't put much effort into designing the Bard abilities for Heavensward and simply copied over their design for MCH.

If Bard had been designed like this from the beginning, say WM was the 30 ability and there weren't issues with proc timing, then I probably wouldn't be complaining. It's just unpleasant losing the playstyle I enjoyed for two years.

I don't expect SE to change things now. Bard is functional and not being excluded from content. I suspect the cast times were purposefully added by SE because they felt the ranged physical dps were getting off too easily with having less to worry about than other classes in terms of positioning and timing.
Perhaps it wasn't fair, but I enjoyed 2.0 Bard while it lasted.
