This is also not the case, in all the calculations for conversion above are what was calculated to ensure players Kingdoms remained at the same point, using resources that existed prior to 9.2. This is not comparable to how much Kingdom XP Crystals are individually worth, then how much of that you need to level a Kingdom as well as you need to meet the global population requirement.
Whereas if someone started playing from 9.2, the experience is completely different to get to level 50 (access to resources, needing to upgrading Kingdoms to ensure you are meeting global population, etc).
Again, this, is not correct cos you are only looking at the resource values and not considering that you also need to have the required Global Kingdom Population. You can’t just sink all your resources into one Kingdom to get it there, without also upgrading other Kingdoms, to increase the global population.
