Dungeon list of boxer difficulty?

[Syferr]

Black Rook Hold First boss is the killer in there, ive cleared it on Mythic after heaps of wipes on my guys i ended up soloing the first boss from like 50%.

The spiders in the stairwell are almost as deadly as the boss.

I tried Court Of Stars yesterday and completed the instance on regular Mythic. I wiped all but my main on the first boss but still was able to kill it from around 75% with one tank. (Starting to realise the beauty of having a few DK's in a team for battle rezzes).

Second boss went down ok after a wipe because i ignored/ didnt see through the 5x consecrates that there was stuff on the floor i shouldnt be in.

Last boss was a one shot but could see it being a pain if it dosent go down fast enough the more mirrors of himself he spawns.
