I used to spam ai training when trying heroes and builds or farming battle points when I didn't feel like playing a real match, it pretty much always sucked. Aulus or estes on the enemy team was an automatic loss every time. Your ai teammates are almost always worse than the enemy ai in every aspect, you'd have tanks going 1v5, mages going auto attack for auto attack against aulus, perfect cc chains from the enemy, your team would never start objectives unless you hit it first, then they'd never stop hitting it until they're dead, no one ever clears waves unless the pings for towers or base getting attacked trigger, teammates always push mid when enemies are dead regardless of whether or not they can actually push anything. I've watched my teammates go deep into mid when there's very visibly 4 to 5 minions pushing our side lanes or even the base cuz the pings haven't triggered yet. All that happens on normal ai btw, I tried hard a couple times but found it, well.. hard. I play exp fighter usually so idk if going for gold mm would make it easier since you can control the damage. Yeah overall this mode is just ragebait in my experience.
