How do you use your specialists effectively? It seems to be that to gain a bonus from a specialist you must sacrifice either some food, hammers or commerce to gain the specialist, and this is only worthwhile in certain situations. For example, is it better to let a cottage grow to town, or to sacrifice that worker and instead get a scientist specialist? Downside is you lose a fair bit of commerce from the town, but the upside being the get a nice supply of beakers... doubled if you run representation, and with a Great Scientist coming along eventually to build an academy. So should specialists be micromanaged carefully, or left to the AI? And what about other specialists? Engineers I never seem to use, and the game has an obsession with placing the, in my opinion, rather useless priest specialist in many cities. A good reason not to let the AI automatically pick, I suppose.
