its simple, you agree to the rules with time/server and first clan who attacks, it doesnt effect any outcome of the prep.
i actually think its good from PX to step up and come with an actual prep proposal, but u seem to think thats an advantage?
now its been years that de defending clan can pick the map they want to defend on, so stop being being so broccolied, you wasted everyone's time + u lost a prep where u had the chance of winning.
