Like seriously how are people okay with skill styles being purchasable? It should come with the damn DLC which you ALREADY have to pay for. If it were free, sure. It's not free.
Someone here mentioned antiquities. It's not the same. You pay to get access to the area, not the lead itself. The only leads you can't get are from the latest area which you can get literally every other. Now imagine having to pay per lead even in older areas.
