I have a Bleeding Elementalist: GRIMTOOLS…have to bring it to 75 first.
But I think, you mean Druid, and Yes, I already have one: Bleeding Druid
Maybe SR 80 possible, with support from Wendigo Totem and Dark One´s Grasp. Though no such defense as Seal.
Edit:
Only killed Mogdrogen on my Trickster but on Elite. Ravager I made the wrong choice, I took the one with Aether Damage and Fumble (…of Minds?). And Trickster didn´t have enough tankiness/ADctH to beat him.
