To be honest, the stats as are now are how they should be, so we shouldn't ask at all for them to go back as they used to be, but for the early opening of the instance after Brothers Farewell (the one that requires around 40k power to open that drops red natures and all the others red tools), so that all the reforged item made so far due to this obvious bug would become very quickly obsolete and pretty useless for the people that got them due to this bug.
It's the only way to get the situation solved in a fair way for everybody.
