You should not have an advantage, because you have PVE friends to carry you through. Cough Cough, Asmongold, Cough
Nor should PVE give any advantage in PVP at all. We have been complaining about this very thing since Ion took over.
The Raiders, will not put up with for a SECOND some BIS dropping in PVP, did you not see how hard they flipped over CNS? So what this reads is, PVE to PVP, or BFA 2.0.
Also from another post, we see that top pvp gear is once again behind 2400 rating, so hella geared PVE players, will severely outgear, and lock arena down. You either get rating high week 1, or dont bother.
