Too update I've been leveling them as 1x unholy (tank), 3x frost (DPS), 1x resto druid. Very fun team, I've spent alot of my time just tweaking setup but the outland instances ive done were just a joke, my shaman team cried at how easily the DKs could zerg through everything. After a single rune rotation (~10 seconds) the entire pack is basically dead from AOE ~0-10% hp left on average

Really looking forward to hitting northrend instances
