I see now that the idea of an 85 spawn area is gone forever. I do however, want to at least recreate the "landmarks" of those successful areas:
1. Long, clear lines of sight from a dominant, commanding, somewhat concealed positions. Areas that are fought hard for, and difficult to knock the enemy off of.
2. Areas of prime, excellent cover that you can fight over.
3. Opportunities to rush a gauntlet to gain an advantage.
4. Confining terrain features that channeled or bottlenecked GV play.
There are no areas anywhere in the AH3 maps that have 1+2+3+4. And I just have this really strong, deep belief that when there were landmarks present in a past evolution that lead to positive outcomes (even if they were the result of happy accidents), you should do everything you can to repeat them in future evolutions.
I'll keep experimenting.
One last question. Is the placing-an-object-in-the-terrain a hard and fast rule, like you can't place ANY individual trees or bushes on a terrain, or is there a count that you have to stay under per square mile, etc. That would be helpful to know.
