I don't usually use one anymore either. It's kind of funny, one of my guild mates has several realm first type titles and he never displays a title. I have another guildie who has the Magic Seeker, realm first Malygos title, and he puts it on every time we go into a pug....I guess so people won't think he's fail? I really don't know, but I do chuckle when I see him pop it on.
Oh and...I am tired of the guild rep title prefix as well. It just makes guild names of your guild mates WAY too long.
