I was getting that - I figured it was my internet since I have been having problems with higher latency than normal since the patch. Normally not the ability lag though.
This is no excuse - Blizz knows exactly how many players came back as they are getting paid by each of them. Blizz needs to spend a tiny percent of this income on replacing/upgrading their servers to handle the additional load. If they are expecting players to put up with continuous lag in all outdoor zones just like we had throughout Dragonflight, I hope a good chunk of the player base leaves, and lets them know the reason was lag. I’ve already cancelled my sub because lag simply ruins the game for me, and made it very clear why.
