I'm a bit confused here, you're saying that there have to be boss fights of some sort, but then saying that you can use whatever tool you want, and there are no limitations, but also that you require strategy.
I think you need to iron out a better judgement ruleset, as I know that I for one am not interested in joining a competition and dedicating my time when it looks like the winners are just going to be decided arbitrarily.
It looks like calvinball.
