What two rings did he have specifically? If he had Garuda and Allagan (or Hero's and Garuda), the Ultima Fending Ring is something to get (Garuda's is just a bad ring for tanks; I can't wait to get rid of mine). Its also arguably better than the Hero's Ring outside Coil (7 DET/14 Parry vs 16 Acc/11 Parry) or if you don't need the Accuracy.

So, no, I can't blame a tank for grabbing the Ultima Fending Ring. Its a very good ring for tanks to have.


Also, he did participate, and since he was a tank I have to assume he didn't get carried (kinda hard to as a tank in that fight), so if he could roll on it its his right to. You said nothing about lotting rules, so you can't really complain about it.
