Not Hospitals but...

Forgive me if this has already been suggested but I'm too lazy to use the search function.

Instead of creating a healing system units/buildings that increase unit health, give us 2 simple options. Allow like units of like level to be combined together to replace lost health (The current system of combing fresh units with damaged units only gives you one option that reduces the overall speed and contributes to the stack cap). Secondly, add a disband option that scraps your units but salvages some of the original resources used (inc manpower).

These should be proportionate to the units health in question. Ie lv1 infantry 15/20 health combined with lv1 infantry with 5.1 health would instantly produce lv1 infantry with 20/20 health and a lv 1 infantry with 0.1/20 health.

Likewise disbandment should refund 50% of the original cost and this 50% would also be dependent on the HP. For example a 15/20 unit would get 37.5% of the original value back whereas a 5.1/20 would get 12.75% of the resources back.

Can anyone let me know the harm of adding these features? They just seem like a much needed QoL change to the gameplay.
