Enrikk and I both tried and were one rounded.
It was fun but based on the zone, run, swim, zone, swim to get to the mob, how hard it hits and the fact it may or may not be possible to kill the loot table doesn't add up.
Suggestions are as follows:
1. Please confirm posted loot table is correct. If so 3 of the items are not worth the kill(17701, 17702 and 19070). The other two items 11584 and 11588 with the difficulty of the mob maybe add a type 17/18 slot to each item and make them no drop.
2. Lower the amount it hits for. Taking damage between 163k - 327k is a little insane.
That's all I can come up with. It was fun finding a mob that may have been unknown that was outside of the Tier raid system but wow..
