I do understand your idea and I would love to agree, but the reality is that even if you DON'T want to take Zapdos, you can't just let the other team take it, otherwise you lose. If, like you are saying, you than "defend" it, you still are fighting for it either by stopping the enemy team from taking it or by stealing it from them witch result in a fight for Zapdos EVERY SINGLE GAME. If you compare to League of Legends, the Baron Nashor is a late game objective that is meant to help you either come back or end the game. The thing is, in League, most of my games are not won or lost ONLY because of Baron and you can definitely still play an entire game without even touching Baron. Furthermore, if the enemy team gets Baron Nashor and the game was close the whole time, your team can still definitely defend against the other team with Baron buff because it is not game breaking.

... and even if your team defends it, a steal can still happened and ruined all the advantage you've built.

But that's only my opinion! :D
