I don't really know your situation or anything, and to argue a single player versus the concept of this is going to be a waste of time. Ir Yut is a 3 minute fight. When we finished it, it was 3:08 on our encounter timer. Unless you have a group or set of toons that can't do it, but that brings me to my next point: Skipping anything in what was obviously a cohesive linear series of bosses is "Cheesing." And the only reason we call it "Cheesing" is just because people didn't want to call it "Cheating" so it doesn't sting as much.
