Please do not, BM lives from bitter sweet revenge stories.
But as I said, Bara’Khur isolates itsself quite a lot in re last weeks with that Mordoc thing, a conventional attack would have come sooner or later anyway and maybe even not from Angmar.
I also wholeheartedly invite you to join Angmar with Tam or a fresh character in case Bara’Khur falls or any other time.
You will see not everything is as evil as it seems.
