The ability Commander's Strike that you can get from Battle Master costs an ATTACK, reaction point, and the targeted ally's reaction point.
This does not match 5E rules. The 5E rules say bonus action instead of reaction. This works out to be better because typically bonus actions don't cause damage, but reactions can cause or mitigate damage.
I propose making this ability use an Attack, Bonus Point, and targeted ally's bonus point instead of reactions. This is closer to 5E and it doesn't cost THREE potential damage resources to give one.
I would also increase the range of the ability so the utility can be used better. This will allow you to use it to prioritize a more wider range of targets. The rule in 5E is see or hear distance.
