Enemy attack animations...
This is kind of a minor thing and I've really only noticed it lately ranking up PGL on lower ranked mobs... but some mobs (like jellyfish.) cover alot of ground with their normal attack animations... so when I am locked on to them and they do their attack they actually move passed me and my camera spazzes out to follow them, then my character does a nice pirouette to keep the mob "in front."
Can we maybe tone down the mob movement? just have them whip me with their tentacles instead of bum rushing a preset point 5 feet in front of them (and 3 feet behind me.)
