In reality, I think wargaming has to suck it up and begin adjusting some premiums down. Multiple tiers are effectively ruined because of a few ridiculously unbalanced tanks that they stated they will never touch. They are constantly messing with tanks at tier eight, when the real problem is about a half dozen Soviet premium fantasy wagons. If they brought the entire tech tree bottom up to compensate, The balance with every other tier is simply thrown off, leading to a rippling cascade of sadness and horror.
All they would need to offer to end any complaints is a limited time straight same value gold refund after any patch in which one of those tanks was nerfed. They wouldn’t lose any money because real currency has already been exchanged for in game currency.
However, my bet would be any such implementation would wind up at some cockamamie half value or less refund and then explain how you should be happy to get it.
