I think would be difficult is to keep track of who should and shouldn't be on these servers. It could very quickly just end up being 2 jail servers.
The distinction between the servers would be so hard to keep, I agree.
It's just going to turn into 2 servers.
There's no rules saying "if you don't know how to play, you can only play on this server, if you're good at this one, you can only play on this one."
Not only is no one going to really understand what is going on, but, quite frankly, no one is going to care if there's a server to help new people. All they're going to see is people they can dominate over.
Admins are not on all the time so it's going to just be another server with more problems, more rule breaking, and with rules that are so unbelievably unregulated.
While I love the idea that people who are all new are learning together, wouldn't it be confusing to only be around new players and not understand what all is going on? You'd have to have a teacher of some sort.
Where would you get them? The other servers? Where they could be learning by example anyways?
I want you to kinda imagine this happening and the chain of events that everyone will have to go through in order to make this all happen.
In the end... it all is pretty pointless.
