One of the more annoying elements of any online gameplay is grinding for an advancement, getting there and having that moment of satisfaction spoilt when that Shiny New Thing you just bought is nonfunctional.
Suggestion is to implement a pinned thread in the Bug Reporting forum which list all classes / skills and their current broken / bugged / functional status, with a link (or links) to any relevant bug reports for each skill. Status updated regularly as issues are resolved. Call it State Of The Game or similar. The baseline format could be the same as the Global Character Stats page.

Re: Gameplay: Broken and Bugged Hitlist
It's a good idea, possibly better served by maintaining a wiki page, where just about anyone can contribute and update a skill's bug status, rather than post here and hope a dev has the time to update the pinned post/thread.
