I think the single biggest loss is going to be the community. Isolated boards may work for the specific fans, but hopping across to see what other fans are saying is largely lost. That is something I personally would miss.
I haven't got an account over there myself, just read it from time to time when a big story drops, but does Total RL forums not already have boards set up for all the clubs? I know a few clubs have already made their own now but i would have thought that would have been an easier transition than everybody creating their own. We would still have the community side of it over there too like you say if it is how it appears.
