Might I suggest keeping the balance change for another ticket ?

(Should be fine in this case if it's just dropping of one not so relevant inconsistency and is mentioned in the commit message)

If a reviewer/committer wants to split it up, that's fine. Just need to add this to the six files:

<Cost>
  <BuildTime op="add">3</BuildTime>
</Cost>

Some strange inconsistendy that I noticed, when building a foundation (f.e. a corral one) and double clicking that, one select all corral foundations and not the fully build ones. When doing the same with walls, one selects all walls (foundations+build ones). Probably unrelated since any civ has it.

Also unrelated triple clicking does make the difference between "barrack" and fort champs (or ship vs whatever), don't know if that is intended.

I noticed both of these things and guessed that it's because if there's no selection group name (or if you triple click), then it uses the template name instead. Since foundations add "foundation|" to the front of the templates, they won't match completed buildings. However, if you have a selection group name for the building, then the foundation inherits that, so they will match (unless you triple click, when it'll use the template name instead.) But I didn't look at the code to see if this was actually how it was done.

Another revision could perhaps also remove the rank from the group name for most citizens healers and dogs.

Well, you could remove the '_b' from the selection group name of every promotable unit, but it's not really hurting anything. Was there something wrong with healers and dogs in particular?

(healers and dogs have ranks too, but for another revision though)
