This game is made for everyone to win and so people don’t feel bad that they cannot get a 50.People actually think SR130 means something when it doesn’t mean anything except you’ve played more.
Actually, the 1-130 levels are just your specialization progression. While some players mistakenly take this for a “ranking” system, that’s not the case. In fact, 343i will eventually be rolling out the TrueSkill ranking system in the not-too-distant future.
In the meantime, you can check out Halo Tracker if you wish to view your actual rank per playlist.
