Is VSF possible with heros

Hi I saw a youtube video with someone doing a VSF with two accounts and heros but there wasn't any info and after searching around I still havent come up with anything.

is this still possible? I think it was done in NM but that dosen't bother me I want to do some farming with a friend and looking for places where we can go duo.

also I just wanted to check does evenyone in the team need to have compleated EOTN to be able to enter slavers exile or if one person has is it enough? (I say this because my sin hasn't yet and cant really be bothered to if I don't need to)

many many thanks

Yeah, that's how VSF originally started.

Oh cool how come there is no build for it on pvx is it not very good? what would be a fun run for two people?

also on a compleately different note I often to uw planes solo, what would be the best uwsc to go as ? and is it as profitable? more fun? than going solo?
