Since Tormax as it is announced is going to be significantly less populated, just shift the rules to make it a OOW/DON era locked server. The people who want a non free trade/random loot server will still play on it; most of them will quit during POP, and the remaining population who want a DON/OOW locked server will get their wish. It's pretty much a win for everyone. Also: the people who don't care about DON/OOW lock will just be on Teek, like most people, so having this server as a DON/OOW lock won't impact them or their enjoyment at all. Let's go
I would suggest PoR stays level 70 cap, gives you more content... I would play it if it were also FTE.
This is my point... even people who think a don lock (or oow, or even lvl 70) is a bad idea would likely agree that it's better than just a plain-vanilla TLP. we've had: Phinny, Mangler, Aradune, Coirnav. There's been 4 of those basic TLP's already. Do another era lock, I dare you!
