enemy cast bars (antagonist) and bigwigs ?

[Tucciim]

I don't know if i am just being blind ro what but it seems that i can't see any enemy cast bars during boss fights. this is especially bad during the shade fight in kara when i'm supposed to be kicking. it's to much of a pita to watch the top of the screen for the bigwig notices. does antagonist get disabled when bigwigs kicks in or am i just missing something.

enemy cast bars seems buggy at best at normal times anyways. it picks up all the red players casting but doesnt work that well on mobs. anyone else having that issue?
