Suggestion: allow injuries to heal over time.

I hope positive injuries wouldn't stack...

If positive injuries were "balanced" with an associated -1 trait like I mentioned, it would at the very least give the illusion of balance, but hey, I can see it being more trouble than it's worth. Still, I think any injury/title/medal should have at least some basis within the mechanics of the game...

Deep Blue, what do you think about this idea:

Maybe these other types of effects could be linked to the random events, to make them even more interesting and impactful.

Well random titles or rewards are interesting (sort of an "epic" drop in a mmropg) as it gives "old" players a reason to brag

I would also like that for example every top 10 you do your units will receive a title or something. Or a title that lasts 1 week and it is refreshed every week if you manage to make it top 10.

ie: the first one in the ranking for one week has all its unit having a "medal/injury" with the name "Champion"

one week names are not exacly motivation for me - i want something constant to be interested in it ;P
