This is clearly one of those events designed to reward those players who can spend a lot of gems. I know S8 have to have them from time to time. I recall finding the Baron's birthday event frustrating and disappointing. So I will play this one casually. That won't be hard, given the return rate and speed of the alpacas and sheep. I shall go into 'barely playing' and just enjoy my kingdom. There's always lots to do to build up resources aside from the times goals.
