Here’s what I’d love to see for playlists at launch, or shortly after. Please don’t crucify me if I left anything out by accident that you liked.
In no specific order:
Warzone, including it’s Invasion variant
Classic BTB with a mix of the following Slayer and Objective modes:
King of the Hill
Big Team Slayer
Community Spotlight Playlist:
Includes a community made game variant and map variant. 343 selects a few different creations and lets the players vote on which one they want featured for a few weeks. This process repeats for as long as its feasibly possible, with a new community creation being rotated into the playlist every few weeks.
This all seems like a lot and I don’t know if 343 could even fit this all in but if by some miracle they did and had extra space then it would be cool to see some party modes.
