I understand your reasonning with extra attack. What you said is what I had in mind. If I'm not wrong nothing prevent you to use a weapon action as an extra attack so it should work as you described.
I checked a bit combat maneouvers but I didn't tried in game for a long time : I don't remember everything, fextralife may not be up to date and things may have changes in game.
That said If I'm correct all manoeuvers damages are increased by the superiority dice roll.
Weapons attack damages are reduced by 2 or cap to 1d4 while maneouvers damages are often (always?) increased by 1d8. Consideribg this : do you still think manoeuvers would be outshadowed by weapons attack ?
What spells or class-ressource based actions do you have in mind ?
About ST disadvantage they were not in my list at the beginning. I added them to allow more synergies between characters. I guess it could be less powerfuill with a flat malus to ST rather than an advantage ? (Let's say -1 or -2).
Not sure that's something I can do... I could decrease the DC but it's not the same.
Thanks a lot for your feedback !
Can't wait to read what else you have to say
