Did you guys watch the same video I did? Yes, ok, you shouldn't jump out of an AOE, but he was very clearly out of the landslide long before it went off. It's really not ok that the game plays like that. (I do notice a marked improvement in Titan HM since the patch myself, though)

One suggestion I have for you is to take a look at how fast your hard drive is and adjust your visuals down as much as possible if it's a slower drive. I reinstalled FFXIV to my faster HDD and lowered my graphics and now I have this type of problem much less frequently.
