Category & Playlist Arrangement and Global Rank Suggestion

I would like to propose to re-arrange the playlists and categories for the June Update. I feel that some of the playlists are in weird places then where they could be for the best. Here is my Arrangement suggestion:

> >Ranked
> -Lone Wolves
> -Team Slayer
> -Doubles Team
> -Objective
> -SWAT
> -Snipers
> -MLG
>
> >Social
> -Social Slayer
> -Squad Battle
> -Invasion
> -Multi-Team
> -Big Team Battle
> -Team Classic
>
> >Co-Operative
> -Co-Op Campaign
> -FF Limited
> -FF Arcade
> -Score Attack
>
> >Action Pack
> -Action Sack
> -Grifball
> -Infection
>
> >DLC
> -Noble Map-Pack
> -Defiant Map-Pack
>
> >Community
> -Community Slayer
> -Community BTB

In order to make the addition of playlists in Arena to work more properly I have thought of a good Global Rank system to give people an incentive to try all the different playlists in Arena.Here is my Global Rank suggestion:To earn 1 Exp you must win 1 match in the designated playlist.

> Ranger
> -Earn 25exp in Lone Wolves
> Ranger Grade 1
> -Earn 50exp in Lone Wolves
> Ranger Grade 2
> -Earn Bronze Division or higher in Lone Wolves
> [Challenge: Earn Gold Division or higher in Lone Wolves
> Cr Awarded: 80,000]
>
> Cavalier
> -Earn 25exp in Team Doubles
> Cavalier Grade 1
> -Earn 50exp in Team Doubles
> Cavalier Grade 2
> -Earn Bronze Division or higher in Team Doubles
> [Challenge: Earn Gold Division or higher in Team DBLs
> Cr Awarded: 90,000]
>
> Askar
> -Earn 25exp in Team Objective
> Askar Grade 1
> -Earn 50exp in Team Objective

If there is a Global Ranking system like this then it will encourage players to compete in Arena and try to get into the Top Divisions. Because you receive high amounts of Cr for complete the Rank challenges, people will be more inclined to do Arena.These are my suggestions for playlist arrangement and Global rank system.

So you basically want the playlists the same as Halo 3?

And Invasion a social gametype, its the best gamemode on Halo: Reach by a long shot
