Here's the proposed feature list for anyone that missed it: https://foundryvtt.com/article/v12-patreon-vote/
I'm not a Patreon voter, but my take is that I'm much more interested in the 11.5 stuff than the 12 stuff. My experience is that the parts of Foundry that frustrate me are WAY disproportionately oriented around module management... Running the game is already pretty great. The module-compatibility-checker and built-in backups seem welcome additions on this front. Though I think it hasn't gone far enough until the compatibility checker is driven by user-compatibility reports, similar to https://appdb.winehq.org/ . What we need to see from the version-checker is the summary of user reports for a given module/Foundry version pair. I'm hopeful that they'll improve the compatibility checker in future releases, but I'd love to see them jump straight to a proper user-report-driven compatibility db.
For the 12 features, I'm most excited about...
- (5), manual fog-of-war. This solves so many visibility frustrations when calculated vision causes some problem.
- (6), placeable items. Though without the stretch goal of bundles I find it of limited use. Fantasy Grounds has item parcels that provide similar functionality, and they made prepping and distributing loot a breeze.
I'm cool with additional media features and will use them occasionally, but Foundry is already beyond the limits of the "production values" I can support for my game. Using all the existing lighting, sound, and media features overwhelms my prep time. After having experimented with a few high-production set pieces (that the players and I really enjoyed), I'm scaling back to rely most on basic maps/tokens and imagination. This streamlines the media side of my prep a lot and is a lot more sustainable for me as a GM. I'll still do big productions occasionally, but a few times a year as a memorable event. And Foundry provides 95% of what I want for that already.
