I think the function of Accelerated Crew Training can be further improved if we could select which crew member the exp. goes to. The Importance of a commander, driver and gunner takes a higher priority than that of a loader and radio operator thus if we could give the exp. to them we could accelerate the crew training faster on the crew that we need than those that we dont. Also tanks with a large crew a much harder to train than those do not so it can also solve this problem.
And yes I know that this will lead to Imbalance in crew skills in tanks...........
