Another thing to check into is what cross class skills you can carry over and use with your WHM later. This is by no means something you need to worry about RIGHT NOW but when you get into end game content you will want to make sure to level Thaumaturge to unlock the skill Swift Cast so that you can instantly use Raise in the heat of battle. Arcanist also leads to some useful skills down the line as well. But like I said, save these things for later and just have fun for now.
