Were they all swapped to accept role-XP as imm-XP equivalent when it comes to meeting prereqs?

There is more than one antihero role just collecting dust now because I fear I'm never going to get the edge. I remember when I last tried for it, it never appeared on the list, I assume because of PK requirement.

But it appeared on the list for my characters who didn't want it. That all was before the Great Edge And Imm-XP Nerfening, though.

Most of them haven't, no.

I'll try to remember to go through the list and adjust them.

For what it's worth though, Anti-Hero requires a negligible amount of Imm XP.
