+1 to balancing the skills via a penalty instead of a per/short rest limit.
E.g., you can attempt to cleave, but the attacks are made at disadvantage.
You can charge, but it a) uses (and requires) your full movement and b)provokes AoOs at Advantage.
These changes (as opposed to universal backstab & height Advantage) give more freedom & versatility to martial characters without stepping as much on the toes of the Battlemaster, as the BM can do these things without the penalty and adding extra superiority die damage.
