I'm not a fan of the idea, it won't make anything unique, it will just result in players being forced to switch between servers. It will also cause more players to create second accounts to switch servers with them and I thought PRO is trying to do something against even more multi-accounts.
And you can only see from the comments here what players expect, their own quests for the server. But that will just mean double the work for the staff. So we will need longer to wait to get new content and I don't see any pluses in it.
Starting the whole thing with server exclusivity, I would rather not recommend it.
Personally, I don't want to switch servers so I would be deprived of spawns. As a collector, that would be another slap in the face for me.
