christ, civics should be interesting choices that complement strategy. tools for dealing with deficiencies in certain areas of your empire.
they shouldn't be the end-all completely overpowering make-or-break strategies..
thats why aristocracy is my favorite civic of any that I ever saw in civ4.
You got lots of farms, lots of food, but you're losing money?
ok, sacrifice the food and get some extra money. its a big tradeoff and its not always good, but it is useful for dealing with a certain situation, for a time, and at a price.
I think that when making civics, you shouldn't just think 'ok, this civic is the best civic in this category for players who want to go to war'. It shouldn't be that simple to choose a civic.
They should have a penalty in the same area as their bonus, so that the choice isn't so obvious.
Scholarship is a good example.
Your military units are stronger, but are more expensive. its good for combat, but only for a certain kind of conflict (say, if your enemy is big on melee units and you REALLY need the shock promotion for your units).
Civics should be like scholarship and aristocracy.
