Rogean: PvP Attacks no longer require the attacker to be facing their target.

[Palemoon]

I tested this on Al'kabor and posted my findings, even there (early Planes of Power era) I could be standing back to back against another toon and still backstab. Could swing from every direction too.

Its classic

to be clear, the rogue still has to be at the opponents back to land a backstab, just does not matter which direction the rogue is faceing when he fires it off.
