Throwing my voice into the mix, I’ve been getting severe rubberbanding and skill activation delay in medium to large WvW battles. Not sure exactly when it started.
Playing on Isle of Janthir server from northern Virginia. I’m on 50/25 FiOS so I suspect that the latency issues are on the ANet side.
Recently the latency was so bad that, while assaulting a tower in EB, on my screen we were still attacking the gate at around 10%, meanwhile for others the tower had already been captured (gate broken down, lord slain, and flipped to our color).
