There is a reproduceable way to alter game conditions in a quick match, ladder game. Such as changing the map, viewing your opponents loadouts, changing to High Resources,or even adjusting the game mode to annihilate.
When you've matched with an opponent during the 60 second countdown you can click on one of your elites, then click the "info' button to open the full Elite screen. Then back out to the countdown menu. You now have access to all the regular custom game options and can change anything you'd like before the countdown ends.
