Missing Sub-communities

Comparing this new kind of forum with the old one atm. Doing this, I found it lacking some sub-communities:

1. Bug report - This is a big one, obviously. A place where people can report the bugs they encountered playing the game. However, I could also imagine this sub-community existing and only being disabled for the beta phase?
2. Communities specifically for the individual maps. Might be useful, especially for Gameplay and Strategy and Live Balance.
3. In the same line, a sub-sub community for builds under gameplay and strategy and one for item discussion under Live Balance.
