Incoming change to combat events

I just read this post on the official forums and can't help to wonder how this might work?

Can we please have an explanation how this will affect combat events before it goes live?
I am worried that it might unintentionally break other things like the last few "fixes" that got hurriedly put in an incremental patch.
