Well. Druids are basically human but their genetics allow faster healing and greater control on nature. Their a mix between nazis and hippies....woah man im deep.... basic motto for druids: "You heart the earth I beat the shit out of you." :D
Mermaids are humanoids....>.>
Em elves are meant for archery and are wonderfully fast as well.
Giants are slow but you might want to keep them in mind...especially sexy female giants....0,0
Succubi *plural for succubus. i dont know how much info you have* are wonderfull for stories but they come along a bit cliche.
Emmmm Animal sages come in handy as in dog sages and such. Theyre pretty open to almost all of the animals
