I think the idea of endgame is completely game-dependent. In most, if not all, of the previous years, there were two very clear tasks - the gameplay and the endgame. 2005: Put tetras up high, then run back. 2006: Put poofs up high, then climb a ramp. 2007: Put pool tubes up high, then climb another robot. 2008: Put ridiculously large balls up high, then leave them there. And so on.
As Frank mentioned in his Frank Answers Friday Live at CHP, this game was designed to more closely approximate traditional sports. Much like traditional sports, this required teams to specialize (every team sport has individual players that excel at a certain aspect of the game). With the specialization that comes with AA, there wasn't a need to add a secondary challenge - especially since there were three ways to score points instantly.
Given the way Mother Nature treated us this year, I'm glad there wasn't an additional challenge.
I also think it's interesting that VEX Skyrise doesn't have an endgame this year.
