-Psyfiend that automatically refears you over and over again
-Personal AOE Fear
-Off Heals stronger than any other healer (instants and casted)
-Way to break your healer out of CD's on an extremely low CD (wtf, no one has anything like MD)
-Life Swap (again wtf is this shit)
-Life Grip (and this)
-and just for shits, lets not forget to mention hymn of hope, as if it actually mattered
Okay so, Roots Psyfiend and MC are all on the same talent tree. Psyfiend is retarded and I hate it, but your a dk, not like you can be feared anyways.
If you take MC as shadow and get a full MC off your team is doing something drastically wrong to let him channel 8s (not to mention he won't be doing any damage in the process)
Personal AoE Fear - Priests have ALWAYS had this.
Offheals - been nerfed time and time again and do like 35k not to mention rape your mana
MD - Also easy to stop if you have a brain, or just cross cc it
Life Grip - Would removing lifegrip actually change anything besides make our healers get trapped even more so than now?
Life Swap - Retarded yes, cross ccable nonetheless
I noticed you failed to list a lot of other abilities that other casters have too, but i guess this is the point your trying to make, exaggerate priest control and make other classes look worse.
