I don’t mind a lot of people in some cases like if they are on my server but if I see a bunch from random servers I had never even seen before it’s like “who are these people?!” you know? And even then, people just name change server xfer off you don’t know who is who anymore. RP servers have their identity still to a degree but even then it isn’t perfect perfect you know? Moonguard has their um… “naughty naughty” section but they have their serious RP too. Other RP servers have serious RP too and more horde or alliance based too. Issue is that all servers should have some kind of rep.
That’s the thing with other MMOS they have their own identities per servers like you were saying. Like if I wanted to play on a small server to get away from the “big city” so to speak, you could do that.
