T9 is my favorite coil by far and I think T9 is my favorite music soundtrack in the game. I've gotten so good at T9 I can keep alive in phase 4 for a long time even if the rest of the party is being derpy lol. I know how to dodge misplaced divebombs, how to run away from screwed up fire placements and how to avoid being double iced from screwed up fire placements. Watching other people's thunder screw ups.

You will clear T9 a lot more if you take the initiative to avoid other people's screw ups instead of letting them kill you and bitching about it :P

T13 is bleh... I didn't like the phase 2 music, phase 1 is ok I guess. It just feels like a high stress fight to me and nothing more. It doesn't give me the same feeling as T9. I join almost every T9 clear party, learning party and farm that shows up in PF I even got a reputation for my T9 abilities LOL. If I make a T9 farm in PF it fills up cuz people know me :P
