While this issue isn't game breaking for me as ive managed to clear content so far with no issues, I noticed a few things:

-PS3 version seems the worst with this issue, my friend plays on PS3 and even though I'm kind of expert at titan *eye twitch* I died a lot after dodging attacks with significant time in advance, I did tests in pingtest.net with Grade A results.

-My brother and I play on the same room, I can see both his screen and mine at the same time, and once we were playing on AK recently I noticed the huuuuge time it takes for his actions and mine to show up on both screens, for example, I moved from point A to point B and on his screen it would happen about 2 seconds later, while for some reason his movements appeared reflected on my screen nearly on real time, mind you same exact connection, same CPU, Motherboard same everything with the exception of video card, he has a GTX Titan and I have a R9 280x, so it really doesn't make sense.
