My Guild started progress on Heroic Imperial Vizier Zor'lok 10M last night and encountered this problem:
When boss goes to second platform, 1 tank and 1 healer would follow him and boss just goes nuts. Each time healer enters second platform boss will just melee healer ignoring tank as he wasnt even there.
Here is what we tried:
Sending 3 diffrent tanks to make sure its not tank's fault
Sending 3 diffrent healers
We made sure that tank is in melee range
We made sure that healer is standing 30 yards away (still gets killed by melee attack)
We made sure tank enters second platform first (attacks boss for ~5 seconds before healer enters)
We made sure tank taunts boss (boss attacks healer even when boss was taunted 0,5s ago)
Our priest even used fade when he entered second platform, after 3 seconds of fade boss instantly switched target and killed him with melee attack
Is there some specific way we have to do it or its just bug? Is it possible warlock's gateway causes this?
