The thing is though, that warmane/molten made a good analyse... I used to play on lordaeron AND ragnaros (at one point when I was not donator yet transferred to lord because of queue, after that I saw it was a bad move to only play lordaeron so I played both same time).
The difference was huge, people did not want to play on lordaeron so much, 70% of the people there were transferred from ragnaros because of all the stories that players are more friendly and less ******.
Oh and because people thought you needed less GS for a raid on lordaeron, well forget it...
Anyway, changing realm rates will not make people change server now they are 80. I did not give a .... for the x1 part of lordaeron, I hated leveling anyway. I just heard all good things! In the end all I had was slower BG's which I ocassionally did.
