I'm on Mateus - Aether and was getting severe lag last night. Connection seemed fine in the open world but once in an instance it got terrible to the point where everything would stop moving on my screen and my casts would show the animations but not actually work. I was healing Thordan's Reign and we kept wiping from the AoE spams during the final Sacred Cross phase because my heals were lagging (the other healer's connection was fine)...needless to say I was very upset.
