I was thinking about having another arena available to players much like the tournament yard. So it can be accessed by anybody at anytime and a good place for pk fights. Of course have different room types there, hot, cold, inside, outside, water, in water, air, etc. There can be different scripted goals built in if used as an arena, like capture the flag, or collecting items off of mobs that spawn in the zone, perhaps even survival, mobs start spawning and gradually get harder, your goal is to team up or be left for dead and fend for yourself. if you can survive the whole time, win something.
Several concepts for the arena, that could make it a fun place to spend time. Maybe have an overall goal for it, and it would open it up and make it give different casters etc advantages dependent on the terrain. Thoughts?
