Proof of who was first to beat anything

[Priya]

Unfortunately, achievement data is private by default, so unless people make it public on their lodestones we won't know anything past the first few (BG has been first on coil thus far). It would be nice if this wasn't the case, but so it goes. SE is very protective.

As for the "no-lifing" comments... sometimes world first guilds simply have people take a week or so off work to clear content. I wouldn't just assume everyone there is a "no-lifer."
