If that is the case... then all 10k games in Halo 3 for me were a waist. Just sayin. Reset everything.... but.... 
  
Honestly, if 343i wants to make it huge with the fans, they need to focus on remaking Multiplayer to something like a Halo CE and Halo 3 mix. 
As for the armours, the arm and leg add on's are pointless. Remove em. Return to the Halo 3 Armour set up, but give more options as you rank up like in REACH. Also have some unlocked by special tasks. 
  
Optional ideas: Full color customization would be nice. More color options as well. 
  
Just my thoughts for Halo 4 multi.
