There are always a large handful of people who are the first to shout "THIS ISN'T WoW!" in EVERY MMO I've EVER played.

FFMMO lingo has always been "different" in comparison to every other MMO in the world that calls DD a DPS.
I've entered games before calling tanks {Meat} {Shield}s; and saying "I've got 500 exp tnl" (instead of 2 bubbles to level), and no one jumped down my throat for referencing FFXI lingo in AION, GW, D3, etc etc etc etc....

WoW wasn't the first MMO and did not create this terminology. Just like today's teens didn't create "text talk"... they just think they did.
So the next time someone says something that "sounds" like it's coming from WoW, take a deep breath, remember that there are a million MMOs in the world, and brush it off your shoulder
