What is the best class to farm in your opinion?

Huntress. :P
Maybe not as powerful as a wiz, but you less squishy, and you can paralyse annoying things like levys and constructs

I've been playing a Priest for the last five days and love it. My two main guys are a Necro and a Huntress but the Priest is really fun to play. I guess I need to try out a Sorcerer.

priest if you have trouble living. Necro if you're normal, wizard if you are skilled.

I find with the Priest I don't heal myself very much. Guess I'm use to dodging and sneaking in for the kill. The only annoying thing with a Priest is all the heal requests I get. I do feel bad for all the people dying around me though. If you want a heal from me you have to follow me but that is what most the guys asking for heals die from, following me.

Depends on a few factors. If you are not good at dodging then necro. It sacrifices a bit of damage output when you compare it to a wiz but in exchange for that you get survivability. You can heal yourself for a ton with sprites or constructs. Besides in godlands there's only one silence and it's easy to dodge. You can easily do sprite world and undead lair for the pots too.
I've been playing as priest though because I love holy prot. Makes it way easier to solo harder dungeons and gods. Plus with cwand you mow down low life mobs.
