Which class would run through these PQs fastest

Netts Pyramid...assuming lvl 60+ mode:
-Corsairs (or 3rd job gunners) using icesplitter+Flamethrower macro
-Aran (best in that they can already pwn it in second job)
-Marksmen (since they can snipe the yeti and take only 1 miss and can freely attack for a while)
-Battle mages (stand in one side using #blow) and advanced dark chain+reaper for reach and more free kills, being wary of yetis though.
-Mech (hold down flame launcher button = win) avoid yetis as your normally would on most other chars of course.

Wow thanks for the detailed reply. I wish energy orb didn't hit the little yeti I have a 56 Aran, think i'll give that a whirl
