nado is really shitty for pvm. fire druids are great though, even more so now with 2 new sources of -enemy fire res in rotw.
i can attest to this. i made a wind druid, pimped out.. full gcs/sick nado pelt/enigma etc..the whole nine. That character feels awful.. wouldnt recommend to anyone. Fire druid may be viable, i have no clue. Id stay away from them in general..cheap to make for a reason, they suck so bad lol
