Everything 343 and CA have been doing since Halo 4 has been great leaps forward, but I am definitely concerned that the file sharing/community aspect has been neglected. Frankly Bungie's system wasn't great to begin with, and we should really have evolved beyond itbeing able to have bundled map/gametype options, better use of tags, auto-updating or notifications for new versions, simpler links and in-game browsing a la a marketplace would go a long way to improving the experience.
yuuuup. still holding out hope for things like you mention. amazing that while forge has seem some pretty significant improvements, actually accessing that content has barely changed at all. amazing there isnt some sort of marketplace, ala trials, where you can vote on maps at the very least. ideally, there could even be a dedicated playlist that pulls from the highest rated maps. i'd enjoy a forge playlist with a shit ton of content, even if not all of it was AAA-tier. this would also, rather quickly i'd imagine, weed out the worst of the "highly rated" maps.
