For me, I say it needs to be a hybrid of both, plus a bit more. I'm a no-one that's not enjoyed anything PvP since D2 launched other then Mayhem (becuase well its just spam supers kill and know you will be killed and so what!) In D1 I LIVED for IB week, ran PvP becuase I enjoyed it, ran ToS frequently. D2 launched and have never stepped foot into ToS, run IB only when I needed pinnacles and then stopped playing. And I HATE running PvP everything else. Why does this matter, becuase I could care less how I perform other then get the bounties or quest steps done that force me into PvP for some non-PvP reason and done. BUT - Its all the stupd changes that keep getting made that has made me hate something I used to really like doing and for IB - LOVED. So on Bungo's side of it skill based for people like me that don't care if I die but at the same time do not want to go against to 1% sweater or worse all the damn cheaters in there. So give me SBMM. Then there's the horrid lag issues that makes running against intentional cheaters feel more rewarding then laggers (or when weather is bad so my connections bad and I may laggfor others!) So give me CBMM. But I also HATE going in repeatedly as a solo player against 2 or sometimes even 3, 2 person teammate, I have, in the past been set up against 2 3man teams and of course 4 man teams and in most instances my team is pure solo players. To me thats the WORST! Well the worst till I admit I run for bounties and thus become restricted to my load-out and then face the wrath of evil Hunter scum running whatever the meta is with adept versions, invisible and bouncier then a rabbit trying to avoid being ran over and somehow manages to get 3 or even 4 supers per match and NEVER misses with GoldenGun or as Arc strider or Void Spectral Blades and just simply refuses to die no matter how many bullets me and my other solo teammates but in him.
