Sunken temple Hard Mode

So I went into Sunken Hard Mode with my friend today and when we got to the part where we had to fight the hand and the face where the hand seizes someone, the hand seized me and then went onto seizing everyone else in the party. We died and tried again and this time it got only three of us and the monk was able to kill it alone. with only myself and him alive and I was still stuck in seized mode and I couldn't die or move or leave or anything. We had to abandon out of fear of the next set of hands doing the same as this one. Please fix it! thx!

The hand seizes one person, usually tank, and dps have to kill the hand. If another hand appears, same tactic. Hand is first priority.

If your dps couldn't get the hand down before more people were seized, they either need better gear or better familiarity with optimal rotations. That was a trash encounter, not a boss.

No it is definitely bugged. I did this tonight and the root attack did not wear off even when the hands were dead.
