Should I get the mog sword or axe?

[Frein]

If i had the nuts id get an axe, I miss a lot on my WAR and one miss is enough to negate the extra damage from Ifrits axe

This is faulty logic. There is no way to tell if that one miss happened because you didn't have the +30 ACC. You may have missed even with the Mogaxe, so it's pointless to blame your weapon for every miss.
