I’d go so far as to place it in place of the rogue’s expertise or reliable talent, depending on how big a deal it is. Just a passive, “your allies have this bonus to a skill you choose (that you’re proficient in) when you gain this feature” or “when you and your allies make a group ability check, or when one or more of your allies are using the Help action on an ability check, they treat a roll of X or lower as a roll of Y”
Basically, the idea is that the warlord makes the group better at a task via facilitating better cooperation. A skill monkey by proxy.
Not bad! The trick will be to put it into proper 5e parlance. Is 'goup ability check' a defined thing in the rules?
I also wish there was a Morale stat because a Rabble Rouser would be good at manipulating it. Alas... I wish I had a way to mechanically make that subclass good at undermining authority Maybe as a ribbon I'd give it the ability to create your own cant for secret message talk?
