Halo 5 definitely needs to get rid of armor challenges. if you think about what made Halo 3 so great, you will find that it was the custom games and user created content and not necessarily the online multi-player. Armor challenges in Halo Reach created this need to advance to the highest level and completely destroyed the need for forge and custom games. while i enjoyed playing online, it still bothered me that no one wanted to play custom games and only cared about ranking up. i would suggest that either custom games and forge give you a substantial amount of XP, or that armor is gained not through challenges or accommodations, but through achievements. along the lines of forge and custom games i think that maps should be larger and offer a larger array of vehicles such as pelicans and phantoms, and possibly a vehicle for the UNSC to rival the banshee in speed and maneuverability
