Incorrect title??

That doesn't seem to match up with the Vagabond title though, I have Wise Adventurer (14) and Expert Warrior (11) and that results me having Master Vagabond. All my other hybrid titles takes on the lowest rank like what dante said.

That makes it sound like a glitch.

Or maybe it just works differently than we suppose?

I think it's something to do with the localization. Such as Pyrus's no-wise-title error. We'll see once they fix it in an official patch, but for now, I suggest we should leave it alone.
