I agree with Nort and co. Under the old patch I recently lost a game after having about ten units of T34s surrounded and herded to destruction by group of half tracks, ACs and a couple of tanks in the last turn. That is not realistic. I lost virtually half my armoured force in six minutes to mostly half tracks. That's just absurd and I can't understand why people would prefer that just because it's familiar to them.
With the new rules the game is much more fun and challenging. I love most of the new units and hidden shooters etc. The new assault rules also make you think about things a bit more. I've found you can assault and cause sp losses without actually simply rolling over the defender. This seems more realistic especially if you read about how long some Russian defenders held out during the war against all sorts of odds.
I agree there are a few glitches and some silliness with naval vessels and things. But this is either peripheral stuff or bugs that can be fixed.
