Even on SUCCESSFUL Titan EX runs, every time Titan does his sumo stomp, on my client everyone is knocked back over the edge and then runs across mid air. Obviously on their client it displays with them not in mid air over the edge. Even when the game isn't lagging enough to make moves undodgable it just looks silly/embarrassing a lot of the time.
Just had a friend rage quit and cancel his account last night because of the lag problem with dodging AoEs. I've known him for years, and played enough action games with him to know it isn't a hand/eye coordination OR ISP problem.
I don't understand why more AOE attacks are not like when Titan lands from a jump... make it high dmg if you are in the center, and lower from the edge. If they can't get latency right, at least make it a tiny bit more unforgiving.
