I heard hunters are pretty good, you should roll one of them! Being srs tho, i think shammies are kinda meh. pallies are overplayed, so a druid would be cool.
Enhancement shammy and feral druid are what i play and they are soooooooooo fun....and i love sticking out, and most of the time im the only feral druid in my games, and sometimes the only enh shammy...but now theyre a little more common. i LOVE both though. they can really tear shit up
