I admit that some of the Entropists had RP that could be annoying, but
1. I don't think it was annoying for everyone. A lot of people liked it. I personally think that Grumorumn, for example, was damn funny, and I don't see why it did not fit into the game. It brought diversity, why is that such a bad thing?
2. Most of the time, it was a minority of Entropy that RPed like that. Its just that people remember those chars more than others.

I was never a great fan of chaotic stupid, unless it was done very well, but I liked Entropy a lot for the unpredictability factor that it brought into the game. I think that imms are trying to bring this factor back, and I think its a good thing.
