No, I don't think so. It's still early days, I think we should be building nothing but warriors, workers and settlers until we have
A) at least 3 cities,
B) workers to support them (at least one per city) and
C) enough warriors to properly fogbust the lands to the north and between us and the AI.
If we are concerned that our tech rate is too slow to achieve some kind of Oracle gambit, I don't think the solution is more; the solution is a more achievable goal. MC springs to mind.
Agree as well.
Slight change in where I think cities should go as I think pig/fish (rather than fish/clam) to the east will be viable early. That way we can settle pig/clam to have 2 food resources although only 1 gem. Ideally we need to see whats in the North as well. Not overkeen on settling to much of the jungle early without IW. Plus need pot or writing before our tech rate drops due to expansion.
