Don't mean to bump an old thread but I'd like to apologize to everyone I've indirectly spoken of when it comes to not clearing
I just got hit with a big reality check yesterday when I tried out the Sephirot Extreme I said in my original post that I keep getting Sephirot Extreme to enrage
I can't even beat the dummy in 215 gear and I tried it again in my original 210 gear and I defintly couldn't beat it, keep always getting it down to 4% at most and this is a dummy that doesn't move imagine how bad my Damage output is when I'm moving around constantly? I've pretty much been carried by others.

So I think if I had optimal Damage for Sephirot EX in all those instances where we keep dying on enrage then we could have cleared.
Pretty much stopped myself from going to farm parties until I can beat the dummy legit.
