How hard is Ultima HM compared to other endgame content?

[saber_alter]

Thanks for your input guys, I have a view now of what to do.

Also does anyone have an opinion of allagan vs AF2 gear.

Are they interchangeable according to boss, or does one become better than the other at some point?

coil has an accuracy cap, your goal is to stay above that or very close to that cap so as few attacks miss as possible.

for tanks pre turn 5 its 472. in addition, you want to maximize parry, your other main secondary stat.

allagan jewlery is all BiS, along with belt, and shield. helmet drops on turn 5, along with weapon. everything else is myth.
