I think DaVega's posts are important to read. I didn't agree with several points of his post which I stated but I wouldn't want him to go anywhere that I couldn't keep my eye on him...
Guys be welcoming of a diversity of opinion instead of feeling threatened by it and lashing out. You can debate and outline where you think someone is wrong without making personal attacks.
The biome reduction was a surprise to me too and one I have concerns over but I also am waiting to see if the developers can still create plenty of diversity in the terrain with what is left. Really, the plains biome has been bland and boring since cliffs, canyons, and complex cave networks went away. If anything I would like to see the grassland biome become a simple border around every desert biome as it would help the desert transition better into the other biomes.
