It's the best healing system imo because it allows you to soft retreat units that are on low health and have them patched up in no time on the front line.
Or situations were you win engangments with a lot of entities remaining but on low health, forcing your enemy to retreat while you can just heal where you fought.
I wish the sturmpio heal would be like this, it would allow you to do games without ever setting the medic hq up.
