Ok I just did Temenos North again, MNK 2-hr is easy.
I casted Ni right before he did his 2 hour, so I had to cast Ichi once during Hundred Fists and he actually got one attack thru during his 2-hr. I didn't even bother to switch to evasion gear just stayed in TP/Haste gear the whole time. Definately doable. Got to the 3rd floor but didn't have time to kill any of the Sahagin.
