There are a handful of AoEs where if I hesitate for even a quarter of a second, I'll get bit. Titan HM's plumes is one, of course, but the other ones oddly enough are the Magitek Reaper AoEs in Castrum. I can dodge them about 50% of the time if I run forward or are already running, but running sideways or at an angle will get me hit 100% of the time (likely due to running at an angle in Legacy camera mode adding a tiny bit of additional distance due to camera moving with you.)

I think they definitely need to polish some of their AoEs for their 300ms polling. Apparently they tested it on servers right next to their machine or something. :/
