If all you do is level characters, that's not what an altcoholic is lol. To be honest we don't even have a word for that since its so far out of left field. MMOs aren't for you. The fact that you cornered your gameplay to just leveling cause it was the only "safe haven" to things changing makes it plain as day.
I was contemplating this being a troll attempt, but I'm reminded of poe's law here.
