I have played on a 3x server, and it was fine. The only reason I am asking to increase the xp rate to 3-5x, is simply to allow players to practice their classes, and get a feel for vanilla game-play. In the best of scenarios, I would like for it to be 1x, but with official servers coming back, there is no need for a 1x server. Though I agree with you that the vanilla feel is fragile, the point (in my opinion, at least...) of this new realm is to help people get a feel for vanilla. I don't think elysium expects to keep this server alive once blizzard introduces their servers. Besides, the current population is abysmal.. No harm can be done by increasing the xp rate.
Thanks for your input though!
