What do you mean titles like special in-game titles that only a single player can hold/group of players? And I dunno, I don't see many of the classes meshing well but if you wanted to mix like Magic/Bows I wouldn't mind adding it into the fray somehow.

As for the actual world, does anyone have in an idea in mind? Me and someone else thought up a VMMO a while back which is kind of where I've been imagining all this where the world was inhabited by floating islands which stayed above the clouds and the surface of the actual planet itself was one huge labyrinth maze that went all directions deep into the core where lava was to parts of the maze surface dominated by thick jungles and icy plains. The size would be so unfathomable we could have any kind of dungeon/area we might find. Hidden rooms would be an obvious things as well and since its so big there's no reason to map it out, simply explore to find the bosses, which give you special items allowing you to progress further into parts of the maze (players would find areas where large gates with keys would sit until the player who beat the boss uses a key to unlock it, the bosses respawn so no one can hold the game up but it left the ability for some people to attempt hoarding power over the game itself.) We could have airships and mounts to travel, the floating islands would be pretty big, large enough that they might even have low level dungeons outside the towns.
