So many people go into random battles expecting this or that - a close battle, a high level of play, cooperative teammates.. It's absurd to expect these things, and the people who do expect them feel more disappointed than anything else. The wiser approach by far is to simply accept a battle for what it is, without expectation. That way there is relatively little disappointment. And it's much more likely that you'll enjoy the positive aspects of the game since your mind won't be occupied by frustration and disappointment.
