There are too many Battle temples in the south and the fact the West side is the only side that has access to Archons is pretty game breaking. Red also has a huge advantage with the most potential for uncontested expansion.
Wait -- your telling me the positions in the south have an unfair advantage? And the position in the west has an unfair advantage? And the position in the north has an unfair advantage? And that's all the positions.
Sounds like I did a super-awesome job making balanced -- but very different -- positions. Given that I was working to make positions that played very differently, but each have a decent chance of winning, it looks like I may have done it.
