To everyone saying, "You can't tell if someone is a WoW Player, they don't just announce that."

Yeah... they do actually. They use WoW jargon.

Stuff like referring to their characters as a toon.
Glamour as Transmog
Provoke as Taunt etc.

There's a few more, but it's usually fairly obvious when someone is from WoW if they do much talking at all. Outside of dungeons in social settings they'll also usually say things like, "I've got 15 years experience tanking. I tanked in WoW." etc.

Of course, just because they use the jargon doesn't mean they're being jerks or bad or anything, but man does the jargon drive me up the wall.

Also FWIW, I'm pretty sure the WoW Refugees of prior waves outnumbered the intrinsic FF playerbase sometime around mid Stormblood. They've been coming in for years now, and the initial FFXIV populace really wasn't all that big. It's gotta be something like, people whose first MMO is XIV and WoW players as the biggest sections of the playerbase, with legacy, FFXI vets, and other MMO enthusiasts as the smallest sections of the pie.
