Do you really think there needs to be a LESSer power plant then the tokamak just for the sake of not having to repair it.
I think that we need a leser power planet just for the sake of not having reapair it. And here are the reasons
Lets say that a very experienced player plays op3 very long, and forgets to reapir tokamaks, and tokamaks are lined all around the base, or inside, and they get very damaged, and suddenly, enemy attacks, he uses the advantage of the damaged toka, and disables his base and than destroys him.
or, he just plays too long, tokamaks blow, his Cc dies of damage, and can't build a new building.
