The Nightblade cloak line has been broken since day one and despite regular pleas from players seems to be totally ignored as far as bug fixes are concerned; I'm not sure that there's any point even submitting bug reports any poor.
I'm still having Dark Cloak break inexplicably, not cancel attacks, not work at all (as does Shadowy Disguise) and (one of the main points of Shadowy Disguise) not cancel the Bleed DOT and break instantly if bleeding?
If Zenimax have no intention of addressing the bugs (or don't know how) I wish that they'd just say so I can at least just stop using it and try something else.
It's depressing that a class defining skill is so broken and ignored!
