Jus sayin.

Sorry, that was rather cold of me. I was in a pretty bad mood since I just rebirthed saturday night. Now, let me explain my stance in detail.

I believe the difference in terms stems from the previous name for talents, destinies. Unlike a lot of people (apparently), I still refer to the talent you choose during rebirth as a destiny, since, well, that's what it is. As such, when reading about talents, it's very easy to see "talent" as "talent title", since although the title itself is cosmetic, it's still a representation of your level in said talent. Furthermore, when looking up information on the talent page, I'm only interested in said titles, and the effects having the title available provides.

But even so, I'm guessing the next question is how I could expect a "cosmetic" title to have any effect on NPCs. The answer for that is simple: the talent you choose doesn't have any effect on NPCs either. Or, at least, they don't except in this very special case. So we have "destinies" and "talent titles" that apparently one of them changes NPC dialog. It's not as much a stretch to assume that like normal titles, the cosmetic title also changes the dialog for certain NPCs as well.

So, that's my explanation for why it may not be common sense for everyone reading this. Take it as you will.
