Don't get me wrong, I don't think it should be there all the time either, thats why I said 1 hour / timezone, 2 hrs for each day. Because not only does it occupy players while they do their "five duels", but it will most likely also make A LOT of other players stand there and observe, and THAT will cause a lot less activity in the world, IF it is activated all the time. But not if its only activated 2 hours / day

Exactly. If it's localized and contained to a certain time period every day, then that is absolutely fine. In fact, that will probably be very good for the shard like you said.
