One of the big issues that make the DPS unfair is that the game got a serious shift towards boss burns. In fact, all of these little less than 60 second buffs that make you 100% stronger to burn bosses 1000% faster really unbalance DPS combos. Bosses now go down in less than 10 seconds and while this may be great for farming, it puts DPS like druids on the back burner drastically. The only thing close to getting the kind of speed/damage that a 65+ mage gets with their enhanced Catalyst is the D/R + [Unity with Mother Earth] (which makes all DD spells crit) + [Speed Catalyst] (+20% Casting Speed if not using pots) + [Dark Moon] (which adds +5% Magic Power when it activates), which would allow a druid 2 Earth Arrows a second, but even then how can a Druid catch up to 2 Flames per second? If Mages didn't have that, I could see a Mage DPS build Druid doing some comparable damage... maybe.
If fights were geared to be longer and the DoTs for druids were buffed... oh well what am I saying?
