That's why they have the social aspect of the game. You don't have to go try hard MLG pro to win games. Social was essentially a casual playlist, ranked is for if you want to give it your all and try to win.

Yeah but usually the ranked and mlg playlist always had a small number of gamers playing compared to social. It seemed like a waste

You obviously didn't play Halo 3 in its prime.

I actually did . I was without a job and that's all I did for a year is play halo

Then you should know that both had large populations when Halo 3 was in its prime. If I remember correctly social normally had more players in it, but just because social had more than ranked doesn't mean ranked was a complete waste. Sometimes I felt like ranking up and trying to get that 50, other times I wanted to chill and play the game without worrying about losing that rank.
