I'm gonna say Bard.
Get a

https://wiki.project1999.com/Essence_Mace and you become a beast. I suppose this setup would work with ranger too.
Add in a

https://wiki.project1999.com/Fungus_Covered_Scale_Tunic and you are really cookin'
Once you gear your bard, you can kill many things (without kiting) by slowing + face tanking and twisting heal songs (w/ primary lute) + dot.
I call this setup the "Battle Bard". People will laugh but it's pretty fun setup.
