I'm guessing you haven't been in too many late stage games?

All those games rely on whoever has the most gemgens to win basically.
AC is absolutely a game winning spell as you can hardly dispel it with the amount of slaves you can put in it. Combine it with Armageddon and well, it's game over as there won't be anything left, no gold, no gems, no mages, and than, again, the biggest clam holder wins, for example...

AN isn't a spell that secures you victory, it helps by a great amount but it doesn't win the game for you by far, as you'll automatically be declared enemy of all.

These settings propose an unorthodox playstyle, as ALL the games are about rushing for the chalice and tartarians, along with making gemgen. Here, there is no need for it, and theses settings will demand some other end game strategies besides clamming, wishing and summoning Tarts.

As for balance, every setting you make benefits one and hurts the other nation, there can't be perfect balance.
