No to the notification and waiting period. People are busy and they can't always schedule a time to initiate a conflict then wait "X" hours to actually start hitting.
So you'd rather not know when a GvG is coming in? Arguably this is better following the problem you brought up. The problem is, someone can GvG a guild and be done before they can even prepare. It's far more competitive when both sides can strategize and prepare.
Could just be 1-2 hour notice, some notice is better than absolutely none.
