Agree to the point when you say should it be professional, I do agree and from what I see it don't think it should even be called a MLG playlist as there's so many leagues nowadays that MLG just doesn't fit in but guess that's up to 343i. I wouldn't mind seeing a professional playlist which is similar to MLG settings...
Sword Battles? you got to be kidding me mate, MLG will never have a sword in it because of how cheap and cheesy it is... lol Fun yes but professional when someone comes along and swipes you aint being professional one bit. especially with how easy it is to use locking onto people, just tap a button and bammmm you're dead lol so I'll be nice and say no thank you to that playlist
