Add a Social Doubles Playlist - Team Snipers (S7s Only), Ninja Slayer, Skockets, Fiesta, Kong Slayer, etc.
Ranked FFA - Remove King of the Hill.
Ranked Doubles - Add CTF, King of the Hill and Oddball.
Rumble Pit - Add Snipers (S7s Only), Escalation Slayer (Gun Game), One in the Chamber (SWAT with one bullet in the magazine. Gain a bullet by getting a kill). Remove Oddball.
Team Snipers - Remove Brute Snipes and Shotty Snipes.
Big Team Social - Remove Fiesta Stockpile, Total Control and CTF (theres already enough Fiesta in the playlist and I dont think people really care about playing OBJ in Fiesta anyway). Add Kong Slayer and Ninja Slayer.
Add Monthly Rotating Ranked Playlist - 4v4 Attrition, 2v2 Dodgeball, 4v4 Team Snipers (S7s Only), 8 Player FFA Snipers (S7s Only), etc.
Add Weekly Featured (Rotating) Social Playlist - Infection, Grfiball, Escalation Slayer, etc.
A much more ideal scenario would be to streamline all the playlists (I will link a post I made about that) but with how it is right now, I think these would be pretty good changes to the playlists.
