my party killed it, not impossible, just have to use your brain a little. The ogre follows something of a pattern. as Krausus said, move to the outside when the chains move inside and vice versa. LNC is a good dd for leg sweep and life surge. ARC is an excellent dd choice, but not absolutely necessary. Other party members should try to have raise/resurrect, as this can save your party from having to start over if the healer goes down.
