I haven't had many issues with Titan, or lag in general, but I've seen people die because of lagspikes, even if they know the rotation and react in a timely fashion. My heart goes out to you.

SE should make Titan susceptible to Slow. Give Feint a reason to exist and give everyone an extra split second to dodge. Unfortunately, I don't see it happening, and by the time SE "addresses" (i.e. nerfs) Titan, their solution will be allowing Plumes to be stunned.
