No offense to anyone, but I was doing Titan EX on a Monday with 1-2 second freeze lag a literally every 6-8 seconds. Think I 90k'd 4 times that day as well. I was still the last one standing every time out of the party. Actually one time I didn't live, that was a 20 second freeze lag.. and not much I could do about that.. got a raise (was weird I died on top, so they raised, but lag knocked me off as well.. so I took raise at bottom and still was on top, LOL; just a funny story) and was still the last one up.

Point of all this is, while there is legitimate lag concerns, and bad positional checks on SE's part (ugh melee chasing), a lot of people's issues can be solved by learning rotations and pre-moving. I got out of plumes every time doing this, and I wouldn't even see the animation at times. Also, play at fullscreen in lower resolutions if you are having issues, I have helped many a people by telling them this trick, and they drastically improve for Titan EX just by doing it.
