Well, at that point in the game, any status attributes on weapons are pretty much useless anyway. It has a ton of damage power, and considering how late in that game you get it, that's all it needs.
guess you are right, especially since you should practically have all the abilities and such... I guess the physical chunk of dmg is the way to go, but I thought it was going to be like AMAZING heh, like all the other ultimate weapons for the main characters in FF series. Like Squall's, Lion Heart limit break, and Tidus's weapon which has Triple Overdrive, Magic Counter, Counter and Evade and Double AP(since you gain lvls in FF10)
