I had the same problem as shaman.
I´ve add these Spell ID to the Custom Debuff list 20604 "Dominate Mind".
And make a macro:
Than add the macro to the spell_list with the spell selector.
And its work. I purge two DDs last ID from Dominate Mind perfectly.
I´ve add 2 of the shaman buffs manually:
1st: ancestral fortitude
2nd healing way
If I choose cast by myself everthing works fine.
But if I change this to cast by my class, none of them are shown, not my own buffs, and also not the buffs of the other shamans in the raid.
At this point we have 5 shamans with full t1 *yeahaaaw* and so this were awesome if we will see which of the MTs, DD and so on have the buff up and which not.
A other test with a other class^^ also work for me ;)
I have add weakened soul from the priest and choose cast by all and it shows me, also as shaman, every shield and every Debuff which is up.
Maybe you can check this out?
Thx for that.
