Never seen much reason behind /anon in XI really, don't see the point here either. Hell at least XI had one reason, if you were a whm and not seeking a party you pretty much had to go anon to avoid raise requests from around the globe.

But as far as people finding out what rank/class you are it's not a massive feat to find out.

Chances are unless your really going out of your way to throw me off, I'm just going to check your weapon and average gear level.
