I very much like this. Sure, RPers have, in general (definitely not ALL of us) very little training or assets we would lose, but for those of us who DO it is harder for us to regain those assets than it is for a lot of people who don't RP at all. After all, we have to juggle our RP with our training and money-making, and for most of us, RP comes first. It would take us much longer and much more grief to regain things, because most of us have trained and gained over a fairly long period of time. To many of us, grinding is very annoying, where as to those who only level and mine and duel, grinding is commonplace, everyday stuff, and thus much easier for you to do.
On the good points for the "PLers" who don't like being forced to stay in character, you no longer have to. This new server is yours, it is for the non-RPers, you guys will be the kings, you can tell those who say you're ruining their RP to stfu (and actually use the acronym). Less rules, more features. It should be like going to heaven for you.
