So after a while of playing Ultima HM, fighting for the accesories (currently ilv76, seeking the Fending Accesories), i have noticed a large number of issues when I do the instance with PuGs /DF / some PF parties.

One is that in most of the fight, the healers are running around, out of the range of the tanks, leaving us to fend for ourselves and by the time they're done dodging the plumes, one of the tanks is down, and after the first Aetherial Boom, the probability of survival is already in the mud. Isnt there some position at least one of the healers can take to provide the healing to a tank? As I can see Ultima has no cones or "direct" AoEs, outside of the Tank Purge and Magitek Beams.

Secondly, how many players have gotten/seek the Ultima Accesories? Outside of the usual BiS the iLv90 accesories are, are there any that stand out for certain jobs?
