translation: AR equivalent as starting weapon in Halo 4, grunts, same shit different number.
The fact that you think BXR is equivalent to professional fighting game play, and worry about "unintended consequences" from it makes me scared. Should YY be removed? Should Gandhi hopping be removed?
Dumbing down the game has failed over and over and over again (SMGs, equipment, AAs, etc). Stop developing Halo with this mythical golden trifecta sandbox man-child in mind. The casuals are gone despite blindly following that path for years. If anything, the success of COD and Battlefield proves that players want choice. Instead of hamfistedly forcing ARs down everyone's throat, actually give people some damn options. COD lets you pick whatever weapon you want to use when you want to use it - it's the biggest franchise in the world. Battlefield does the same, and adds vehicles to the mix - demolished Reach in sales. I'm not saying run rampant with 500 guns and 40 perks and all that shit, just let people choose specific matchmaking gametypes they want to play in and let them pick a starting weapon other than ARs.
Following this weird golden pyramid 30 seconds of fun nonsense has brought the franchise to its knees, do something bold for once.
