A More Competitive Playlist

I just purchased and got an Xbox One and just got into playing Halo 5 as well. I have played previous Halo’s and really enjoyed playing in the MLG playlist. I have not used these forums till now. So if this has been answered, my apologies.

Is there plans to have a more competitive playlist like the days of old with MLG as a playlist? Or is anything in the works? I know there is Arena, but that’s not the same?
