Province Bonus to Magic School?

[Executor]

It's all relative. I agree 100% with what Dimaz said.
And this is me speaking from personal experience. I've had games with enc 50% bonuses that I didn't win. I've had games where my enemies had those bonuses and I still manages to kill them. Same goes for any other bonus site.

Sure it can be game breaking, but any number of factors can lead a nation to an awesome position, and nothing guaranties you're gonna win.

Now regarding your statement, as that is what I myself would do, I'd know that there's something going on it that fort.

Usually if someones has a fort with a lot of domes, patrolling and various troops (and it's not the capital), it's more than just another fort. So from that point of view experienced players would probably notice it.

Bonus sites just add a little flavor to the game, as a good player will make an advantage out of countless possibilities, and that's what I love about Dominions, so removing them part by part is kinda like cutting into the Dom soul.
