The campaign is done. And I'm not about to throw another 3.5 years away to do it again.
I think the main problem with my playthrough was lack of personal experience with the game during '39-'41, so I didn't know all the tricks that I found here (I got to the start of '43 in 2013, roughly the same time I joined the forum). So the core wasn't set up to have 5* or anything like what most people manage. It wasn't until about '44 that I understood how experince (stars) even worked, so I had given no thought to it before then.
However, the 5* units I did have (6?) never died and so it seems 45 wouldn't have been very hard had I had a few more 5* tanks and another Me262.
I used flak mostly for its low cost - 4 points taken off a fighter by a SPAAG or 85mm costs quite a bit more than even a whole new flak 128 unit. The 2 fighters I did have did a good job, but I always had to avoid SPAAGs, which were a really nuisance (and there were hundreds in '43, so I don't know how you would keep an AF alive there!)
But overall, the GC is too big a time commitment so I highly doubt I'll be going back (except maybe for Seelowe). But the advice I have found will certainly help in the regular campaign as well
