ngl I just think it'd be cool to have a giant staff that could raise moral but has low damage compared to anything else. to make up for the damage it could have wide swings, hitting multiple enemies at once  with a wider range and boost stats of marines nearby but not to yourself, almost like bulwarks ability banner but doesn't regen shield. The damage could be for example:

Standard: 3
Master crafted: 4 through 6
Artificer: 5 through 7
Relic: 8 through 10

But yeah whacking people with a giant bannerstaff sounded fun, I pray to the emperor this is seen by someone atleast.
