This new alliance system will break SoT. Let me summarize my first experience in Cursed Sails:
My crew of three try to enjoy the new Brigantine. We complete the story line and set off to our first skeleton ship fight. We get there and start battling in a crazy storm that lasted forever. We then notice no skeletons are present on the ghost ships. This goes on for a few waves when an eight man alliance shows up. They sink us and we join there alliance recognizing an 8vs3 situation being near impossible.
We sink the final skeleton ship as an alliance. Not more than a minute later, we are killed and the alliance is disbanded. They form a new alliance and my crew gets nothing. The alliance system is going to cost Rare a lot of fans at this rate with its trolling potential.
