My Dks are only 79 now but the the death rune change is really really noticable with three DKs spamming it. I really like the change.

The second change is the battle rez which i have macrod in my dps spam so when one of my toons dies he gets instantly rezzed and is back in action. In BGs this is total win.

so far all very much having fun with the new changes.
