Speaking as someone who is hesitant to fork over a buck when I have no idea what I'm getting, I notice that not only is the term "Subscription Sets" murky as hell, but there is almost no actual documentation anywhere as to what a "Subscription Set" asset even is. Does it come free with a Pro subscription? Is it something you can only buy if you have a Pro subscription, but it still costs more money? Is it a separate subscription that you pay to an asset provider which gives you access to all their new stuff when it comes out? I did some googling around but google doesn't seem to know much about roll20 "subscription sets" either. And the only thing that I found on roll20.net as a link in the documentation took me to a list of art assets that were marked "roll20 exclusive", but priced individually. Does that mean that a pro subscription gives me access to all assets that are roll20 exclusives? I have to say, I've used roll20 for quite some time but their inability to just hire someone to do their documentation (let alone UI design!) really bugs me.
