If season had more impact things like forest, mountain, waste survival would be much more valuable and interesting and summons like these a little bit more valuable.

While that much is true, it would not uniformly affect the game, due to terrain distribution. So while you are waiting for the passes to clear, your biggest rival is busy taking territory in leaps and bounds.
