No, I didn't use any strategies really. I don't think that I overgear the instance at all but I was able to ignore some aspects of the fights (thank god)

Prince: I came in from the left and stacked my group right behind the tank. When skellies came in i made sure to Holy Wrath to stop them , grab them. MOST IMPORTANT: I added /target frost tomb to the top of a "fast" dps macro. this made them switch right to the frost tomb when it was cast.

Skarvald & Dalronn: I just burned the casted and then burned the big guy. Nothing fancy.

Ingvar: I spread everyone out at max range. I tried to dodge his smash but I could never manage that tanking solo. I quickly gave up trying to stop casting to avoid silence from the roar and dispel woeful strike and tried to keep everyone up and dps him. Even eating the damage I was able to get him. This is where I was shocked I could ignore some aspects.

Thank god. I as getting very frustrated. I will down the Colossus, and Eck next. I will.
