This is a very poor idea. A good server needs a diverse player base and what you're asking for is essentially a "hardcore" server. Think of how much people already complain about pvp on a pvp server because they "didn't know" or because "their friends were on that server". To have a whole server with LESS content? Thats just very very poorly planned out. If you don't like LFR, then don't use LFR. And there ARE harder version of dungeons called challenge modes.
Nothing you're asking for sounds like anything that "the consumer" is clamoring for. It sounds like you want a server where you can feel special in the gear that you and everyone else on the server is wearing.
Uhg, its just such a terrible no good very bad idea. Porbably one of the worste I've seen on this forum in along time. You might as well as for Vanilla servers.
