Hey
I would say that completing Insane in the Membrane was probably one of the most satisfying personal experiences I have had in a game. From leveling a rogue for the sole purpose of farming the lock boxes to staying up late with a group of random people perfectly spread out in an area to mass farm the hell out of mobs for rep. Having to put some thought and planning (Darkmoon rep) into it but still being able to simply go and farm and see myself getting closer and closer with every kill or pickpocket to my goal.
Do you see Blizzard implementing anything on such a scale (even in its current form, not necessarily in its original difficulty) again? Something to put a lot of time into, something niche but with measurable progress?
For those that have done Insane, did you enjoy it? For those that haven't, whats stopping you? Does it simply have no appeal?
