Looking for an Explanation....

Ok I used the duty finder to join a party in progress for the Sunken Temple of Qarn.

The enemy was a Golem and I was Tanking as War. For some unknown reason I could not hold an ounce of Enmity.

After the first time our group decided to let me max my Enmity bar, yet my max Enmity was gone in seconds and for some reason each time the Healer had max enmity. Not only that I could barely get any Enmity even though I used every single skill for Enmity that WAR has.

Our healer claimed I was trolling tank, which is absurd. If people are wondering I've been Tanking since 1.0 and have successfully Tanked Ifrit, Garuda, Moogle hard modes, Darkhold, Cutters Cry and Aurum Vale without issue.

Any possible Ideas on what happened or was happening?
