The "forced RP server" method is just too expensive, as you would HAVE to hire an extra team, and even then, there's a performance hit. Most of the time, GMs of games can go from server to server, dealing with actual issues as they come up; by forcing a group of them to stay on one server, and handle things that are, frankly, low on the totem pole of issues in a game isn't cost effective. Things have to be prioritised, and game breaking issues (like being stuck in geometry with return/teleport not working, items going missing, hacked accounts, etc) are far more important than what you'd like them to be doing; sure, griefers are up there on the totem pole, but monitoring names and all that goes with them are not.
We tried that at SOE for a very brief time back when they brought up Firiona Vie as a server (and hell, even the Legacy server, since it had dedicated GMs), and it resulted in major hits to effectiveness overall for the GM team. If major issues occur, and a bunch of GMs can't get off the RP server immediately to deal with it, it makes the situation worse. Furthermore, it's outright favouritism, non-RPers (who are their vast majority of players) do take not of it and call them on it, and that doesn't work out in the end (see the EQ1 Legacy server, for example) on multiple levels. It's simply just not worth it on their end, and it likely never will be.
