I disagree with this idea, as the fact that you have the ability to server hop is (as far as i know) something that it is fairly unique to Runescape, and is something I am happy to see to continue.
I see what you mean however, when you say that by assigning players to a server you are forcing members of a server to cooperate with each other to create a community based within that server, thus reducing the amount of petty behaviour etc. To be honest, i feel this would not work, as the mentality of a the vast majority of players (in my experience) in Runescape is that number 1 comes first. No-one wants to waste time helping out the "st00p1d n0013s" who genuinely need help and are not being lazy. Sure, there used to be an amazingly tight community within RS, but that was due to the fact that the majority of players were mature adolescents or adults, not the general demographic of players we see in RS today (10-14 years old), who are yet to develop the maturity required to fit in with a community where people are willing to help each other out etc..
I, like many other players within RS already stick to one world whenever playing (I like to frequent world 23), and because of this, i regularly bump into several well known players on those servers (tufftypower, J Mez and G 1 G G 5 to name a few). People like this have chosen to conduct the vast majority of their training on these worlds, and that is their choice, but i feel it would be unfair to confine people to worlds, especially as this would very likely disrupt communities that have already formed within worlds. People who have been playing in the same world for 3 years or so, and were familiar with most of the regulars on that server would suddenly find themselves not knowing anyone at all, and could possibly end up in a world where they are the only mature person over the age of 16 on the entire server (a bit extreme but you get my point), which would be extremely frustrating and could completly ruin the gaming experience for that person..
Your idea is a good one, but unfortunatly, it just wouldnt work.. There would be absolute uproar if Jagex ever tried to implement this, and would kill the game completly.
RS has worked fine for the last couple of years operating over many servers, there would be no point changing the system now. [/i]
