No, seriously. They became so smart that we just got qued into the brawl and the gates were already opened and Ais took 4/5 posts as we loaded in! Currently struggling to take LM back and fighting over others since they armied up some areas. BFA = Bugs For Azeroth. The Ais became so smart they figured out how to open gates early.
The first one I queued into was in the process of losing when I got in. Other than that, the other four I played we won, and it was way less stressful for me than fighting human players (despite how quick the AI always was on interrupts).
The final sign of the end will be when the AI can start making forum posts to complain about balance or why real people get better rewards from BGs than they do.
