It's petty to argue about what exactly the issue is, whether you think your 16-core triple-GPU computer with a dedicated OC-48 connection is immune from it or not. The fact is this problem doesn't happen in WoW, where this style of fight was popularized. There's no reason for it to have to happen in FF14. Also on top of lag issues and animation lock there's a separate issue involving the lava pool hitboxes. You can be outside the pool the entire time, thus not having to deal with lag at all, but still end up getting hit because the hitboxes aren't lining up quite right.
