I was experimenting with AI only matches yesterday when I loaded up a map that consisted of multiple islands with the majority of the map being sea, for the most part the AI handled this just fine fielding boats and hovercrafts along with RED creating a gunship factory, however then we hit late game and YELLOW built a Strider hub. It proceded to build only Dantes, Scorpians, and Catapults (Which were doing more damage to its own structures than the enemy due to being forced to take long distance shots into its own base). It should be noted that the location YELLOW decided to build these Striders was a small island with zero connections to any other land mass.
There were three bots all set on different teams and put on Hard difficulty.
