The AI will use the missile dance itself against my worlds. I find that the AI is not smart enough to take advantage of longer range when it has direct fire weapons and is attacking a planet, even when the direct fire weapon has longer range than the weapons defending the planet.
I don't have a "moral" problem with the missile dance for the simple reason that there are other and more effective ways to defeat the AI. The missile dance just happens to be one that works starting on turn 1 because we all get access to capital ship missiles at the start of every game.
