Is there any compelling reason not to simply merge the "in region" and "in tournament" messages? The tournament is on the tournament grounds, which is in a region, thus you can send messages to all in the region. It's not like the nobles would have been sequestered in the arena!
Because the tournament is being held in a region of a realm that may not want to have its business entirely disrupted by reams upon reams of inane chatter for a week.
If those in the region who
want to join in can simply click a button labeled "enter the tournament grounds" and immediately have access to the tournament chatter, I can see no good reason to force it upon everyone outside the tournament grounds.
