you just said it was too powerful, and too weak.1. Hit dice healing has too many issues to list but I'll make a small list of some of them:
a. In the early levels you can heal more than the cleric
b. The power balancing of such an ability will be impossible. From one perspective it's not adding any daily resources to the party so the parties power isn't increasing. From another perspective it's allowing as much healing in a narrow timeframe as a cleric that spends all his slots on healing. The cleric afterwards is spent. The warlord afterwards would still be just as effective in combat. How do you balance a class that can heal as much as a cleric out of combat but no resources are removed from the class for doing so? (Hint: it's impossible to do so)
Which is it? Because you can add a penalty, or bonus to adjust it.
Scaling up as needed.
It's far from impossible.
Really, just play test it and see for yourself.
some kind of scaling, yes.The tacticians help ability is better but still looks to be very hard for a warlord to scale up with such an ability.
Possibly +1d8 damage, maybe attack and advantage, maybe +int to damage.
