Having a lag of 0.1s is not going to kill you, you need to lag more than that.

This is basically what our group says about this fight. Titan EM is not exactly that hard, the only reason it is so hard is that it's so unforgiving. If you lag even for a second (yes, a second, not 0.1 seconds) at the wrong time, you're going to die, and it should not be that way. Twintania is supposed to be harder, but if you lag for a second, Twin won't kill you.

Most of the time, I have no issues dodging plumes or landslide, but sometimes I can be out of those for one second and still get hit (And yes, I am aware of cast bars, they were at halfway). In fact, I have been hit by a landslide I was never inside of, it appeared in an area I had left a second before the cast even started.
