If you guys have ever played DbD you would know just how broken SBMM is. I agree that it can be horrible for games. It actually gets easier once you get to green ranks, because you're playing with good enough teammates, that you can do generators instead of teammates getting hooked every 5 seconds. I went from green to rank 1, in just about the same time I went from bronze to green in DbD. You cannot expect good teamwork until rank 12 at the minimum. It's pretty sad honestly.
Nowadays unless you play with a team that has good communication you're pretty much screwed. I think the times before SBMM were best. I completely understand why multi-million dollar AAA companies would want it though (no sarcasm). Noob friendly = pump $ into the game.
I still don't understand why companies can't just have regular pubs and ranked like they claim. Even though pubs are SBMM based which defeats the purpose of ranked... but OKAY.
