Any suggestion to avoid those Dominate Mind (DM) like from Arathi Basin's LM down the cliff?
Besides Lil's mention, other tactics to counter those include:
-Block his line of sight (LoS), or move farther than his cast range while he/she is casting. The walls of the big structure at LM help block LoS.
-(As Lil mentioned) Fight him/her far away from the cliff, for when he/she does control you, there won't be enough time to drop you off the cliff.
-If you see a priest DM a teammate, take advantage of the fact that the priest in question CCed him/herself
while DMing. Punish that player.
The first two, among other possibilities, are ways of countering a Dominate Minder without wasting those precious racial/interrupt/hard-cc/trinket CDs.
Oh, if you are going to interrupt, interrupt quickly after the DM was casted, so DM drs with that player if the priest tries to do another DM, unless the situation calls for otherwise (like a priest doing that to interrupt a crucial heal, or possible others).
