Nano, I would like to disagree with you because I think in the case of Free to Play players;
1) There would be a loss of beneficial players, but I think that the amount of newcoming players that would come into the server would be more parasitic to the servers because the chances of them being a beneficial player, in my opinion, is less than 50%
2) Making our servers prime only would in fact mean that the newcomers would have to buy prime, but in that case we can prevent hackers and banned people who get alternate accounts from entering the server
3) Less work for the admins, making it easier for them to concentrate on non-server related things (i.e. Forums)
4) With new players filling up the server spots, I don't think it would be better to have 5 toxic people on or 1 actually chill and non-toxic person on
I dunno, this is my opinion, I think some of the servers should have prime only.
