Different anon, haven't touched it in a year or two, but you'd probably have to do either single player or a private session with friends. Last I heard, most if not all of the official servers had basically been taking over by the Chinese hacker horde. And yes, the DLC-before-finished-game thing soured a lot of people's opinions on it and introduces stuff that completely wrecks the vanilla game's balance.
But there are mods for it (nothing lewd though, as far as I'm aware), and you can mess with the server settings to help speed up the otherwise long grinds. Honestly though, not much going for it unless you REALLY like crafting stuff and looking at dinos.
