I mean if you reroll FOTM just regrind to switch covenants ... Since you're willing to.
Besides the pug scene always excluded people on the dumbest things already, when once you get invited, no one checks your talents / essences / traits / enchants. Like they see a DH or a BM and insta invite, only to find out that he does dogshit dps because wrong optimisation. When instead they could have invited an "off meta" spec that probably puts more effort into their toons since their work harder for the spot.
