I don't think Relic will be influenced by the ramblings or randomnoob123 compared to the feedback they will receive from known CoH experts. Anyone with a closed beta key can register and express themselves in the official forums anyway so that argument is invalid.
I just feel it's better to share all information in one place. That's all.
That's not the point, of course those who are playing this part of the beta must be allowed to talk about it. Just that there has to be a place for those experts to talk about it on their own, as well. So they (and Relic) don't have to deal with those things stated above.
