Casting activity of NPC targets

[TalTal]

It might be because of lag. I am not sure what the conditions are like when you are raiding, but I know on the regular casting bar when I lag alot my spells start casting when I click but the dynamic data from the server takes .5 to 1 sec to start the bar. It then cancels without finishing even though the spell goes off because the spell went off sooner than the bar was programmed to count down to.
