I really miss the setup Halo 3 had with it’s MM playlists. It had a good mix of social and Ranked playlists and they all had a decent population so you didn’t have to wait too long for a match. Also the Double EXP weekends were awesome! I wish 343i would do something along those lines. or like a 1.5X RP playlist or even XP for that matter. They divided Slayer and Objective gametypes and even mixed in the weird game types like Zombies, Rocket Race, Fiesta, Team Melee, Shotty&Snipers, Grifball, and even Splockets.
I want Objective and Slayer types to have their own playlists. Make Arena Objective only and then there’s Slayer for the people who want to only kill. I get 343i would want to do their own thing and maybe use a new avenue of approach but, what Bungie did worked so why not use some ideas that worked and people loved them.
