bosses

hello. I was wondering if some of you played ff12 and actually beat Omega MK-XII and Yamzat, the 2 secret and super hard bosses. The best ive done is bring them to 50% after a very long fight (5hours...) but then either I wipe my pt or boss recovers HP too fast when i try to heal myself far...

Dunno if this was posted of not, but heres a link to the pic of 3 bosses in Apollyon: http://www.killingifrit.com/forums.php?m=posts&q=84681 /drool I'll be fighting them soon I hope O.o
