FFXIV's titles can be a bit... wordy. Combining prefix and suffix titles worked in other MMOs because the prefix titles were generally honorifics and such (i.e. really short). I don't think it would work well here without turning a player's name plate into three lines of text which is a bit much. Most MMOs also don't use surnames, or the surname is treated like a suffix title, so the nameplates here in FFXIV are already considerably more cramped.

I do think we need some new UI for handling titles though. My title selection menu is a horrifically long list now and there is no way to identify where titles came from.
