Ok, today I've been trying to complete arena solo with my rogue. After successfully killing rutger+vortex and stahl+mushrooms, I bumped into glob+enrage. Omg, I threw it away after 5th try. I really tried as hard as I can, but it is unreal to destroy either crystal or boss, there is just not enough firepower to do it within 1 minute. Anyone succeeded at enrage? I doubt. Maybe a little nerf for solo mode? Soloers also want to farm new arena, and they want to do it without praying for non-enrage challenge.
