I was only half joking - i sometimes watch the fights on auto and it seems at times as if the AI is picking the worst possible choice
One enemy left, almost dead? - expect mithrala to use her shield and strengthen buff instead of finishing the job (many buffing champs do this)
Enemy got no buffs?. Doesnt matter to Yasmin she will still open by trying to remove buffs
Hydra head got your champ? expect the ai to ignore it, and also on hydra expect them to focus on the head with an active shield up
Many more examples but wont bore people further.
I know they do not quite cycle through their skills by rote but it feels like it
Having said all that, bad AI helps me in arena, especially with revivers, and at least we can program by wave now so its not all bad.
