NOVA ultimate needs some love - especially with subclassing coming next patch

Diundriel

major maim is just a bad debuff to get from such an expensive ultimate and raw damage cant keep up in pve as well as pvp when compared to other damage utlimates tho the synergy mechanic can be somewhat decent.
But with subclassing coming next patch i see no one in pvp (smallscale or ballgroup) or endgame pve use this ultimate as there are stronger options - and in solo content its anyway a bad option as no one can not make use of the synergy component.

Therefore i suggest the following for NOVA (to buff it, especially for group content and to make it and interesting alternative to other ultimate in group content):
- increase ulticost to 300ish ultimate
- keep damage and synergy as it is atm
- remove major maim and instead add MAJOR BRITTLE for 4-6ish seconds
-4-6seconds makes it powerful for pvp burst and is also long enough for not perfectly coordinated groups to extend the debuff with nazary in pve
-it also shouldnt be too broken as 300 ulti would be really expensive in pve to keep up 100% and next patch dds will be fast over crit cap anyway, sp stacking it with major force becomes kinda useless - it would be more like another warhorn

any opinion on that or other changes you would like to see for Nova?
