This is one thing that really irks me about many videogames in general, not just OB. All the bits and ram and memory allotted to make these games as spectacular as possible, yet we can't make our charactr's name (not to mention class name) longer than a certain amount of letters. This has happened to me several times. All a sudden, everything gets all stingy.
I wanted "Bewjok the Grey Wizard" for my newest character's name, for instance. Nope, can't do it. I wanted "Black Magic Witch" for my 2nd to last char's class name. Nope, can't do it. So I wind up with a compromised name instead.
