Feral MS and Resto OS. I've played all 4 though.
Was resto in vanilla for Pve/Pvp. I've been tank in PvE and Balance in Pvp since burning crusade.
Feral MS. I have a Resto OS which is only used for ICC mount farming.
Well that and the fact that I enjoy healing, so I needed a second Druid because of raid locks - Healing LFR/flex on my main just wasn't enough of a challenge; but yeah, originally I ended up with two Druids because the second was levelled up purely as a herb/miner.
Guardian Main (Feral OS - would love to have a permanent Resto OS but it's just not practical without Tri-spec) and Resto (Balance OS even though I loathe it, as can't be arsed to fix a second set of gear) Alt.
Proud feral here, 8years and counting hopping to Guardian boots when it was needed.
Been AFK for a while, and I noticed this poll almost got 200 votes! Awesome!
Im regularly switching specs as per guild need or my will, I used to be resto/feral @ beginning of SOO but now I am boomkin/bear. Gotta love this class
Loving the number of boomkin! Man, if you asked this question a few years ago, it would have been the least played spec.
If we do not destroy ourselves, we will one day venture to the stars.
