Let's see.
I have a great 6 inning starter, and a lousy bullpen.
You have a decent starter, great pinch hitters, and an excellent bullpen.
I am allowed to decide before the first pitch whether open the retractable dome after 6 innings and let the rain pour down or keep it closed thoughout the game.
What would you do?

Surprised only a few addressed the "unethical" question, only the unasked "is it viable" question.

By the responses, I would assume that it is viable. Why else would so many players hate it if others do it? Perhaps, because if it becomes a major style of play, thier max-buyin style won't be as profitable? And maybe that is why a couple did actually answer the question, and say it is "unethical".
