As noted in the blog post, the pricing was set when we were brand new as a company, and we did not get everything right at the time, and one of the most major parts of that was underpricing render nodes. Because users who have been with us to date have "got used" to that pricing, we are keeping the pricing the same for those who have existing subscriptions and keep those going; but we do have to correct the pricing structure for those who join us going forward.
Scatter was originally going to be a separate paid product :) So that process actually went the other way, now it is integrated in your pricing. So no reason why you would see that be reversed in the future.
Do I understand that it will continue as 3 nodes for current subscribers then?
I understand charging for more than 2 nodes i suppose. But many independent artists like myself have a dual-machine setup and its become quite normal to work on one and render on the other. It doesnt really feel like we're using it as a render farm. It feels quite necessary these days.
