I just don't see the point in it – inventing things for the Guinness Records as a whole, not just getting more FFXIV stuff into it. It becomes a contest to invent the most infinitely specific category you can think of to get your name on it.

"First to clear X content" / "most points scored in game X" type achievements are best left within the game's own leaderboards or achievement logs, not duplicated in a labyrinthine new system just because you can.
