Super Unit in Heroes 5.

Secondly, there are many ways to maintain balance without making it too easy to acquire this powerful unit, and I'm not fixating on it. If you don't like it, that doesn't mean you should stop there; come up with your own super-unit that won't break the balance!

Yes, yes - secondly, a super-unit as such is not needed! Because it is they that ruin the balance: you find one, and you basically get a level 8 monster - too bad for the second player who won't be able to have such a unit. Therefore, the conclusion is - super-units are not needed in principle!
