There's a player on FFXIV's Japanese servers that's a B1-level mahjong professional, and he keeps an account just because FFXIV has one of the better multiplayer mahjong clients. He didn't get too deep into the game itself or anything, just got to where he could unlock mahjong and shows up to games at level 18 in merch gear. Imagine getting into a mahjong game against some guy with a bunch of stuff around him that screams "newbie" and getting flexed on like this.
