As I've been scooping around I found a little discussion about the planned healer unit. Here's my thoughts: The aforementioned discussion brought forward the idea of a moving healer unit which could be brought along with your army. The healer(s) would also auto-heal. I don't think this is such a good idea. It could easily get over-used, and even though you could make some artificial limit (like the healer having very few hitpoints) to the usefulness, a healer is in my opinion a defensive unit and should not be brought along in a fight. Another RTS I've played (and still play alot, since it's great for multiplayer games - you can save MP games), by the name of 'The Settlers III' have healer buildings which you can gather soldiers around, and then units would go one at a time and get healed (if they are close enough). This is more in line with my perception of what a healer, or a doctor, should be like. Still, this has some limits. While it's great for Settlers 3 to do it this way, because you have actual borders and towers all over the place, for 0AD with no borders it could easily become annoying. Let's say you take your army with you, and a worker which builds you the healer's building. After the battle, if the building still is there, you would in 0AD have to feed the healer or crush the building, making for lost resources. So my idea would be something in-between: let's say you make a healer unit. He(/she?) spawns with a backpack on his back, and then you could make him set up a tent wherever you want. You would of course then have the ability to make him pack his stuff again and move to another location where you would need him more. He would auto-heal units close around his tent being in an idle state, either one at a time rather quickly, or everyone around in a small area in a slow manner. What do you think?
