Back to maple, need a little help deciding

So im back! Im going to be playing in kradia, less people, from what i hear a good community. I wont have any funding pretty much, i know a couple people there that might help me out, but idk. So i need to know what class to pick, it needs to level pretty quick ,and not cost a ton, but i can find money for pots if i need too. Clerics level fast, but i mean, do they still level the fastest with training places other than mp3 out there now, i can see then not being #1 anymore.
