Another SMN here, let me say that I LOVE this class for all the reasons listed. It's a very busy job that has you always thinking because of Dot timers. The ability to apply Dots, contagion, bane and Fester is glorious. Using Engineer plus Rouse and Spur for solid AOE damage is icing on the cake. The only real weakness IMO is burst DPS, Fester is just not enough considering how long it takes to set up. You won't always have adds pop right next to the boss to apply bane either. Overall though I am VERY pleased with SMN and that includes my floating jello Egi's
