I'm not sure what was the developer's aims behind. But I'm not really thinking they wanted to make it easier to manage. More like making it an economic burst to try upgrading epic insignia to legendary?
500 of these damn "insignia powders" actually cost about 600k AD and raising. 10 epic insignias, cheapest 75k each. Drastically raising now...
Plus the cost of the price of the epic insignia wanting to upgrade.
In comparison to the quite static price of legendary insignia from the ZenStore-Boxes this will now be the only economic relevant source.
Great PayToWin, crashed the working system.
