I could be totally wrong (small sample size), but it seems like they fiddled with the AI on PVP.
Thor seems to be using his powers WAY more than before. Maybe it´s cause I never pumped my IM40, and my team has no sinergy due to having to use him, but I lost more battles on the Double Shot tournament in an hour than I had lost in like two weeks. He just keeps pumping those reds and yellows.
Given that the AI has always used every special ability as soon as it starts a turn with enough AP, the only way you would see it pumping it more is if it simply happened to be getting more matches of the required color (red / yellow / green in Thor’s case).
It’s possible that the AI is choosing to match colors for its abilities more often in cases where it has a choice - I haven’t studied it closely enough to tell. The AI I’ve watched the most is Venom, and he seems to prefer purple > city > black > green in my nonscientific experience. Maybe Thor was the same way, and is now less willing to match environment tiles. FWIW, I can say that the AI still fails to recognize 5-tile L matches, as of just now.
Shrug. Okay then. FWIW, I’ve pretty consistently watched the AI use every ability it could, as soon as it started its turn. For… weeks (I started playing when Steam offered it). It never delayed for me. Now it delays using all sorts of things.
