There is current a bug in the arena system which can be used to disconnect one member of the opposing team. When two types of CC hit the target at the same time, one causing you to move without control, and the other one which stops you from moving, the target DC’s.
This was tested with a Warrior/Paladin 2v2 team. Once you get the timing down you can pull this off every time.
Paladin Hammers the target, and then the warrior fears as soon as the hammer hits.
In theory this should work with kidney shot + fear, frost nova + fear, and deathcoil + frost nova.
From our testing, it only seems to work in arena.
Enjoy your easy matches.
