According to the in-game "Combat Attributes" display, your inherent stamina continues to boost your recovery while in Nova form. The icons also remain in your buff bar.
They do work in forms. It hasn't been fixed in mids.
And it's dreamy. Having Stamina from the get-go in Nova form is absolutely brilliant. I've found it pretty much impossible to run out of Stamina on my teen nova form.
Quick-fix in mids, most people don't toy with the database editor but you can do some good changes with it.
Options -> Advanced -> Database Editor.
Select Main Database Editor
Find: Warshade_Defensive ont he far left column.
Select the above, find: Black Dwarf on the far right column. Below that column, select 'Edit'.
Choose the Mutual Exclusivity tab along the top of the new window that opens.
Check the box for 'Skip Mutual Exclusivity for this power.'
You can now toggle dwarf on with any other powers.
Click 'OK', then back in the main window find Warshade_Offensive, and beneath that find Dark_Nova, and repeat the above steps you did for Dwarf.
Save & Close in the bottom right.
Be warned, though, this will let you toggle ANY power on with these. Even both forms at once. Unfortunately, I don't know how to edit the mutual exclusivity grouping rather than just shutting it off.
Just remember that while in form: No toggles will work, and neither will absorption. You can benefit from Hasten, the inherent fitness pool, accolades, eclipse, either mire.
If I discover how to access and edit the grouping files to change what's excluded I will update this with instructions.
Wow thanks for all the great replies guys, got good news and more info than I bargained for. I have messed around in the database editor before, I'm sure I'll figure it out!
I'm sure I'll get assaulted for asking this instead of trying to find it on my own, but I could have sworn they made inherent fitness work in forms? According to mids this isn't the case. I recently read dechs' MF'ing WS guide and I thought I'd take his tips into Mids to see if I would enjoy a WS.
