Oh great, the scouting argument again.
So each game in a tournament should be played in a private, soundproof booth so no one else can see or hear - intentionally or unintentionally - a participant's tactics like "roll attack dice from a Falcon" or "use PTL with Fel."
The only "scouting" I'd take issue with as a TO is the guy that shows up to the event walks around taking a look at what everybody else is running before sitting down to build his list.
