I play multiple characters at same time so I have multiple screens to look at so I have a slight advantage here. What I noticed if my main tank isn't having the hitpoints recorded close, I just look at another screen and it will most likely have the hit points close to correct. I can see this would be harder problem to fix since it has potential to update differently on each computer in the same fight.
It is annoying to have the mob's health at nearly full health when in reality he is near death or even dead!
