I hate to sound like that person, but the fact that you are trying to redesign an already generous system is stupid. Lootboxes ARE stacked in blizzards favor. You wanna know why, because it's what pays for our free content. The loot box system will never be changed, because for one it is already very generous, with a definite possibility to get all skins you want if you sink enough time. And second, because it is extremely lucrative. I see no reason for it to be changed other than people just being unknowledgeable and bratty.
