I'll give you a scenario of someone with higher latency making it through Titan EX. I have a member of my FC that lives in Scotland. Due to his sleep schedule and such, he's usually awake and online when we're all online, which is during NA prime time. It took him a few tries but he did clear titan ex, and a number of times after that as well. He just had to anticipate when the attacks were coming. It was funny listening to him on TS trying to dodge though lol
