The Waterfall base is in a pretty bad spot right now. It is a 3 wall base and has nothing going for it. It is smaller than most 2 wall bases. It is possibly the worst base in the game and I think that it needs a change.
I propose that the fenced off area be changed to an island. The idea is to have a tree growing out of an island on a lake which is the base.
I was thinking of putting a Tree of Vigour on the island and so it would give it some benefit to the base.
I also propose that the island will be reachable through a ramp and thus give more space to the base, which it desperately needs.
I think something like this would be satisfactory. http://i.imgur.com/PodkqXo.jpg
