I hope I can say this without getting flamed.. But I really don't like Fang in battles.

Am I wrong for this? I think the SAB role has limited use against most enemies (except bosses, and those don't even get debuffed sometimes..), and I find the SEN role a tad frustrating. Her one redeeming role, COM, is also extremely weak. Am I doing something wrong? I hear all these people talking about how Fang is a powerhouse, and I just am kinda lost. Anyway, I've heard she's rather good for wiping the floor with Barthandelus' second form (the one shortly after Oerba), and I'm beyond frustrated with both her and that part (I've been stuck there for probably a month). Any advice?

Thanks!
