I know you can filter certain spells but what I mean is interrupt announcing. Namely the {Boss ability} was interrupted by {person name} is really useless to show (for some people) as you have nameplates that do this or you have chat announcers for that. It also clutters a screen as it's not that important who interrupted it. Either add it to each spell separately or global disable (or both, which is better).

That is used just once this expansion and it's for Motivating Cry. Not everyone has something that announces interrupts and it's useful to see if someone interrupted it unexpectedly.
