Custom league purchase.

full disclosure i have posted about this before in a way.

Let me start a league with more options not just crap options that make it harder.

increased loot,quant
pack size
always {insert league} on map.
boss's spawn randomly.
100% increased moddifiers on map etc

honestly just better options..

clicking any option that increases loot or rates and or makes it eaiser or what ever disables charecter migration, disables achievments.

I do not care if i keep my items
I do not care if i get achievments.

Why not?
Honestly someone answer why this is not a thing?

"i can only think of one reason and that is GGG doesn't want to see people having more fun in these leagues"

am i wrong?
