I know CRS is afraid of a "red vs blue" game, but I don't agree at all that it would be like that. Each side has different variations of similar equipment that make them different enough to bridge the gap between identical and inbalanced (with a couple exceptions). For example, the 3H and Stu are both T1 tanks. The stu is fast and agile, the 3h is slower. The brit rifle holds 10 rounds in a clip, but takes longer to reload. The k98 holds 5 rounds, but reloads quicker since it only has to put 1 clip of 5 rounds into the weapon instead of 2 clips of 5 rounds. The mp40 fires slower and accurate, the Thompson fires fast and maybe a little less accurate. You get the point. Red vs blue would be reskinning the same exact tank for both sides. same speed, same gun, same armor, same sap spots, same commander binoculars, etc. Same goes for inf weapons. Every successful world war 2 game that I can think of has game balance and none of the players complain about "red vs blue".
I am not a new fan of the "historical" storytelling approach, which is why I unsubbed after all these years. I'm paying the same price to play with less equipment for a forced storyline attempt. And with the tz3 pop imbalance, maps aren't even lasting into the later tiers that often, limiting even more equipment.
Also, tier 0 and tier 1, as many above mentioned, drive off some players too. Takes around 2 weeks just to start getting the "fun" toys. That's half of a month. You have to wait around 3 weeks total to get to the even better ones. Once again that's 3/4 of a month! And if the campaign ends before that, the timer resets. Another 3 weeks minimum. I think they should just start in tier 2 or tier 3. If some are afraid of the change, start it as tier 2 and make it a longer tier 2... say like 1.5-2 weeks.
