I would argue that the one-shots and live shows are a consistent improvement/feature of the Patreon, plus the bonus exclusives, with the only major content loss being Blades. Inconsistent months are a simple given - unless Rollplay becomes a multi-million dollar business, there's gonna be weak seasons every year due to the nature of the medium and people involved, etc. For other big budget show production in the "biz", shows have very deliberate off-seasons anyway.
The way I see it, year 1 was a successful experiment, but it revealed numerous flaws within their strategy and business model that they had no foresight on. Ambitious promises and such being what they are, they were diving into new territory largely uninformed. Year 2 is an effort to restructure the business model into what year 1 should have been had they been able to see into the future. Regarding the $1 tier specifically, JP has said on many occasions in the past year that he undercut the value of the rewards too much.
In my opinion, I think there should be a bit more transparency, and it sucks that the base tier has changed. But I think restructuring the business model is overall an intelligent decision and that recent content issues haven't been a reflection on JP and Adam's commitment to making Rollplay the best it can be in their eyes. Hopefully JP has plans in place to improve his "scheduling and commitment" system (considering he wanted to hire someone for just that, I imagine he does). With regard to unsubscribing from the Patreon - it's chiefly a personal issue for anyone that has to consider how they spend their money. Vote with your wallets and spend wisely.
