CatLady look at the replay and provide the time and location of specific engagements that you think were unreasonably bad for ships. I had a look and generally the bad engagements look reasonable given the forces or counters on each side.

In reference to B560764 2 on Shimmershore v1.0, I'm going to decline to draw any balance conclusions from a 1v1 in which both players made a Scylla by 15 minutes.

If you don't understand which decisions can only result in you losing more metal than your opponent, the outcome of the game is determined by your lack of understanding, not factory imbalance. Understanding that Scylla is a poor investment is a way easier task than understanding which ship vs amph engagements you should take, let alone which units to build and how to manoeuvre them to cause good engagements to occur. If you don't understand the first then I have no reason to think you understand the second, let alone the third.
