To quote yourself.
So Kargon likes to get really technical in his discussions, and he is right to say it is possible, but also he said probable and possible are 2 different things. What you have described is not taking it slow, it is like deliberately going out of your way to avoid any progress, you need to not do any season journey, avoid all legendaries that buff your power or not use that power, avoid the cube etc etc to keep playing on that low level for so long. From your post history it does seem you do know your way around in the game, so for me it doesnt seem probable that you went out of your way to avoid any progress, so like your own quote i think you lie to exaggerate.
