Been having way way way more consistency with yogg druid than with yogg mage. I really liked my yogg mage deck. Initially I was doing very well, but as time went on it would seem like if I didn't get flamewaker in my first 5 cards I'd just get eaten alive by aggro...which is a majority of the ladder it seems. There would also be many a game where yogg and tony would be in the very bottom 5 cards of my deck and I've done all I can to stall out with ice blocks and frost novas.
Fast forward to yogg druid. Probably the 2nd best class for spells after mage. Good mix of direct damage and board clears. Better draw. Ability to armor up and heal. Win condition with savage roar if you have a few bodies up...made easier with mire keeper and violet teacher. And then you still have yogg for the come from behind / sebukku finish. Which unlike the mage yogg seems to help me more often than kill me on the druid. Eh go figure...having way more fun this way.
