Fought my first level 6 AI Ankylon titan today but was disappointed to see it never use its fourth ability as I slowly reduced the titan's HP. Same thing seems to occur on Vorastra AI never creating phase tunnels but saw a Ragnorov fire novalith rounds when sieging planets for quick assaults. As for starbases, it never once activated the Safety Override Protocols when the Argonev was soon to be crippled even though it was set to Auto-Cast. There might be other abilities not being used but these are just the ones I noticed.
