a long time ago (during early 5.4 ptr), I remember a few posts about a so called "warrior questline" about becoming a weaponmaster, or something like that, and that it would involve high overlord saurfang. what has become of that?
Never hear of it. But it would be nice with more class-specific quest lines like the green fire one for warlocks but I don't see it happening anytime soon, but who knows? I know I'd love something like that for my paladin or shaman.
