Generation 5 introduced the team preview feature to WiFi battling. This basically erased the lead metagame and the fine arts of scouting and team prediction, while introducing more planning and (debatably) making the power creep more manageable than it would have otherwise been.
When people think of the fifth generation they typically think POLITOED, but to be honest I'd argue that team preview was a more important feature than weather.
