Yes I'm suggesting a pande mission terminal... Please read the whole thing before flaming. Everything rolled is a hard mission, and the missions are NOT always complete able due to the high random-ness of them. You can't copy keys, no scaling of difficulty, and the mobs are completely random. They are spawned in random locations, so yes all of the mobs may be in the entrance when you zone in and it would suck. Also they all are unique, i.e. some with 1k damage shields on 2 or 3 damage types, 100000 NR, healing. Put a boss similar to a Zodiac at the end of each level and let it drop Zodiac loot at a lower drop rate. Maybe put in some aggro wiping mobs as well?
I'm just trying to think of something that might be fun to do, with existing game mechanics so it's easy on the devs, and that won't get TOO repetitive with all the randomness in the mission, and still maybe fun for a 220 even though they are not SKing, but give decent SK as people will most likely die and not complete these missions. And put the mission entrance in pande garden, we hate to travel :P
