Credit revision, please explain

I also left my Heavies alone for fear of going more in the deficit.Side Note, the format did not retain for the posting but know the format is 1)vehicle, 2) Credit Earned, 3) Credit Expended and 4)Balance after repairs and replenishment.

So, what I found is a drastic change to gross credits earned since the induction of version 7.0. As an end result, no longer will I use consumables except repair kits as the credit system is horribly tweaked against us. I agree that perhaps this is a sales technique to get players to buy more gold to build up their accounts. I was already spending on the average of $50.00 a month, sometimes more, sometimes less, but about that per month. It allowed me to buy gold ammo, convert experience to get next tank and buy the occasional credits when short for next vehicle. However, to have spent about 3 hours getting first victories on the above tanks and writing this narrative, I only gained a 27% profit in credits. That's insane nerfing! Granted, had I survived all of them, would have made a bigger difference, but in version 6.7, I was easily making 50-60% gains in credit profit each night, so there was plenty to spare.
Anyone from the development team care to elaborate on future changes?
