Personally my merits are gonna be;
8/8 Marksmanship
4/4 Evasion
4/4 Parrying
4/4 Shield.
So I figure I'll benefit more from sword than from dagger, if I use a main weapon at all (Other than Fire Staff, I mean).
I'm definately going to get a Martial Gun, with all these good ratings you're all giving it! That, and I apparently parse 100% RACC in meripo. :s
