some raid bosses questions

has anyone done bosses like leto chief talkin?
they got minions with names that sound like they are healers (seer)
wonder if its actually a healer or a nuker minion

Leto chief has two healers IIRC.

lenty of bosses have healers
when you do them you have to decide if it is worth killing em or not (just like in pvp)

they heal. and they have some buff too. not sure which one.

According to you-know-what, those seers heal, buff Might and drop some arrows.

btw Nakondas (the wyvern near gorgon flower garden) has healer minion too, the succubus.
