It's RNG. Let me tell you of a story, of a game I played long ago, and still play to this day: FFXI. There was a certain piece of gear I wanted for one of my jobs, and it only came from a specific zone, within a specific endgame activity. You know how long it took me to get that thing to drop, let alone actually secure and acquire it? [b]It. Took. Years.[/b] Multiple years. This game has been out for less than 2 months, by comparison. lol
