Hello.
I know ICC has only been around for a few months now but I've been wondering something. Are there any intentions or even slightest plans of Lordaeron progressing further and when I say this I mean upgrading server to Cataclysm expansion. If this was the case I'm aware it's not gonna happen any time soon, but once 3.3 content goes fully on farm and players get bored of it, maybe? Anyway, I'd like to know if there's even a smallest chance of this happening.
Nope, that won't going to happen, because of 2 reasons.
1 - Lordaeron was a server design to be WOTLK hardcore server, this is from 2015 news.
2 - If you played here like a year ago, you may have known that there was a realm called Warsong, that realm was Cataclysm PvP and they closed it, because of low population, as you can see also on Neltharion realm, what I mean by this is that Cataclysm is not a popular expansion here and Lordaeron would suffer alot and would bleed even more population if it turned out a Cata realm.
Though not everything is darkness, I heard some time ago that you may be able to transfer your character from a previous expansion to a realm that has a more recent expac, but still Idk if that is true though, I would like to know that from the devs.
Either way I hope my answer was complete and clarifying to you
One realm can't simply transform into another. WOTLK can't simply become Cata due to its differences in cores. Once they make a decent Cata realm there might be a possibility of transferring chars to it.
