It's Official! Backstabs are Back!

Maybe this will also discourage people to rely on backstaps in pvp, though it remains to be seen how it would work against another player. Quite frankly, I welcome this new backstap mechanic. It made the game WAAAAAY easier then it had to be.
We still haven't seen anything to parries, yet. I wonder if same changes has been made to parries and ripostes.

^ That. There still is no Word on Parry/Riposte

I think the change is great for PvE, not so great for PvP. As the only time the i-frames matter in PvP is when outnumbered. If gank squads are possible again they'll be even tougher to deal with solo.

But the PvE implications are wonderful, between these new backstabs and the more dynamic looking combos weapons are doing combat looks to be shaping up to be quite engaging.
