I don't know if this has been mentioned before, but I've noticed that the enemy tank AI is pretty idiotic. I recently set up a game of 3000 points, giving myself only a crack platoon of Tiger tanks. I set them up behind a couple hills and waited about 10 minutes, then I brought them out and started blasting at the T-34s at long range. The T-34 crews basically just spun around in circles, exposing their vulnerable side and rear armor, while firing harmlessly at my Tigers. They made no effort to actually use the T-34s superior speed and attempt to rush my Tigers. They just clustered up in a big group and spun around in circles, making themselves cannon fodder for my Tigers.
It seems that whenever an enemy tank encounters one of your tanks, and it has superior armor or the gun on the enemy tank is too weak, the enemy tank will slam it in reverse and spin around, exposing its flanks. Once it gets out of view of your tank, it will 'hunt' forward again, then reverse again once it sees your tank. Or get blown to bits, whichever comes first. Enemy tanks never 'fast' their way forward, trying to get in a killing shot or surround your tank. Your own tanks will often reverse as well, if they encounter a tank with superior armor that they know they can't penetrate, but you can tell it to race forward and try to close the distance with the enemy tank. The problem is, the enemy tank AI doesn't seem to ever want to do this, and just keeps reversing.
This problem wasn't as apparent in CMBO, apparently, because the two sides were fairly balanced in most encounters. Having either superior guns or weaker armor, so they didn't spin around in circles like a lot of tanks in CMBB do. For example: A Sherman and a Panzer IV in CMBO were pretty equal in long range encounters, so they would just sit there and blast eachother to bits. But if a T-34 is pitted against a long barreled Panzer IV in CMBB at long range, the T-34 will go into reverse and get itself blown to pieces, instead of charging forward as it should.
So instead of a lone Tiger tank couragesouly beating off a wave of T-34s as they charge up the hill, the Tiger just sits there while the T-34s run into eachother and slowly die. Can't this problem be fixed in a patch or something?
