Found a bug while doing arena last night. When fighting against Ghost if she has a passive crit up (from L1), when Sunspot consumes an incinerate on parry or charging the heavy, it gives Ghost a fury for each incinerate consumed. Ghost should only gain furies when phasing DOT debuffs. If she doesn't have the passive crit up, incinerates get consumed normally and don't trigger a Fury on Ghost.
I was able to duplicate this in a duel as well:
