Thanks for playing! I totally understand the need for more in-depth strategy. While I agree spam-placing buildings can be a problem, imo you can get a lot better results by planning ahead and trying to get all the rare buildings placed, and for that you can also use the faith shop, save cards for later and build according to the resources you lack.
I'll think about this more for possible future updates!
BTW - if you played till the end, I wonder what your score was so I can compare the spam-placing score to the scores I collected from players. For science! 😎😎
