Well actually its not 10 but 8-9 dks on most bosses.
This was done in 4.3.4 a few days before 5.0 hit and changed anything
Since we couldnt do it crossrealm it was hard to get even those 9 DKs and most of them were twinks or badly undergeared. We still managed to do 4/8 on heroic what was more than i expected.
With 10 highly geared DKs pretty much anything (maybe except spine) should work thats why i plan to do 25 dks vs DS HC soon (you can still sign up for it link above)
This part includes:
Ultraxion Heroic: with all blood it seems that just the 2 who are tanking get affected by fading light
Warmaster Blackhorn Nhc: simple, simple.. simple...
Spine nhc: couldnt try hc because we did some bosses nhc before still not that easy
Madness nhc: way easier than expected but we got mad last phase and thought just ignore any tentacles and nuke him what almost made it a wipe^^
