First of all I did what you did and posted a question in 2 different forums awhile back. Turns out that experienced players who are the ones that will be answering your question can see all the new questions & threads whether it be in an email or whatever. So they just see the same question twice. I was told it’s a bit annoying but now you know.

I’d personally use Vampire Hunter but Piece of Mind is a little more versatile overall. Not sure what talismans you have but they are super important when building a team. I make a team I think is good with the right combo of talismans and do well in PVP for a day or 2 then they suck again and I have to change it up so I don’t know if anything is permanently “right”.
