Well, the 28 levels didn't really take me very long. I quite like leveling so I'm not too bothered about that.
I would wait for the server transfers but they are going to operate in much the same way as WoW free character transfers do and they will be trying to get people off big servers instead of letting you move onto them.
I'm also tempted to play Cleric instead of Mage, so I have proper tank and healing options for LFG, etc.
Yeah I'd expect the transfers to operate that way too, though I could see maybe a forum led agreement by many different servers to all move to the same one to form a high population one.
Certainly like all the options available for characters (not as comprehensive as Daocs 30+ unique classes, but its definitely more flexible than many MMOs), currently I have a Cleric (lvl45), Warrior (lvl45), Rogue(lvl29), Mage(lvl30), 2nd Warrior(lvl29), 2nd Rogue (lvl23).
