One major issue with this suggestion every time it's brought up, it needs dedicated programming.
And it's not some small little change like "oh, it just chooses the best option for color transformers/explodes or targets the weakest troop/biggest threat, etc."
We're talking redesigning the AI to be smarter. People already hate the AI for "cheating sky drops" as it is! If loop teams started working endlessly for the enemy, then good luck dealing with Alchemist, Hellcat, 2x Goblin Rocket teams, they'd be a guaranteed death sentence.
If the AI was ever able to be made as intelligent and informed as a human opponent, I'd rather go for real PvP because then I can at least hope for human error to kick in.
The upcoming gem sliders are probably going to be the closest we get to "smart" AI, and I'm okay with that. But even that's taking enough effort on the devs part to hold off until 3.1.0 or possibly further away.
If the game had been made from the ground up based around a more intelligent computer, then yes, I could see something like this working. But with the troops we're presently stuck with and other details like weekly boosted troops, it just would only fit to make the game more frustrating than the occasional sky drops and lucky devours already do.
That's my thoughts on the matter, at least.
