I dislike the Halo 4 ranking system honestly because it feels like it was half-assed, like they could have done better. Halo 3's was the best, as it took time and skill. Getting your trueskill level up is pretty much the same as CSR but it literally has no effect on your rank in-game. I spent a lot of time trying to level up to a 50 which I never was able to but still it kept me playing. I feel like I'm gonna go back to the older Halo games when I hit SR 130 in Halo 4, maybe try to get my 50 in Halo 3, as I'm a 44 right now. In Halo: Reach, all you had to do was play A LOT to rank up, which I did, but it still felt like they could do better.
