To people who are saying that they don't experience #3: you're full of it or simply aren't paying attention.

Every person in my FC/LS has this problem. There is an odd delay on boss abilities (red zone telegraphed attacks) of about .5 seconds, meaning you can be out of the red area before the cast bar finishes and you will still get hit. The same applies to supposedly "instant" abilities like Shroud of Saints, though some instant abilities always work, well, instantly, such as the WHM 30% healing buff. This is a major issue that needs to be fixed.
