Tbh, I like the Sirnames. They give a uniqueness to your caracter. I dislike the idea of "optional" Sirnames. The first reason is the fact that it removes half the point of the sirnames. To stop players being called (lame examples) "bloodkiller", moving to "blooodkiller", to "BlooodkillerxX" etc

Also, The argument that people feel "forced" to pick a Sirname is a mute point. Until now, other MMO's have forced people NOT to have Sirnames, due to only having the first name as an option. For this fact, I think it is completely fair and reasonable to have one MMO which impliments Sirnames as standard
