I love the surnames so yay! Really is it that hard to come up with a surname man laziness...

Also if you ever do first "The Horn and the Hand Faction" leves they actually poke fun at the people that try to use Sephiroth as their name and mention at least 4 different ways people to try to write it before the NPC gives up on trying to remember.

And besides just because right now there isn't a use is no reason to take away a unique and harmless feature of the game I mean now your just nit picking.
