Can we just not have them or remove their reclaimability?
All they really achieve is messing up an early build every so often cause a dead tree was in the way. You can never actually reclaim them as they fade exactly when your first factory is up. Really don't see the point of having them other than annoying people and making the first factory be a smidgen closer to spawn. I don't think any map balance is that precarious...
So I say remove them or let me build over them.
Or give a good reason why they are round.
Cheers.
