Sry for not replying, just saw the message on the panel.
And in sorts its not really a free world, its a deserted piece of forest(no people but there are some animals) where heroes fight each other in team combats. 2 bases cause it will be a 2 team combat map.
So, no cities, but i think caves would be fine. And as for the healing doodad thing, its okay, thanks for the idea. Although i'm not sure what doodad would be good for it.
Thanks for everything and sorry for a late reply.
