Oh, nice. Thanks for the info. I'm not sure I'd want to do that insanely long TF again, though.
As for the AV fight, I'll pass. I'm a casual player, and I don't even try to fight AVs solo. Well, except Dollface, but that's a special case.
Do you actually have to fight Dr. Vahzilok in the second part of the Positron TF?
I remember doing the original version way back when, and there was just an eidelon elite boss at the end, but the missions have changed significantly. I'd rather not start the second part if there's an AV fight.
