New class, where do I quest ?

[NathCim]

Yes. You still have several options though. Your guild will have new quests every 5 levels, you can do guildleves, guildhests, the hunting log, F.A.T.Es, and running dungeons for xp. Plus you get a +50% bonus to xp earned

He has Conjurer on 32, so he will not get the 50% bonus. The bonus takes effect after reaching lvl 50 with your main class, afaic.
Best way to level the other classes is to get up your main class at 50, then push via leves and hunting log to lvl 15, go dungeons (while waiting as dd, do more leves or find a fate group, as healer or tank the time for finding a group via duty finder isnt really long).
