Why do Some Argue Against Skill Based MM?

DeviouslyCursed:  THANK YOU! You just admitted a major problem with SBMM! You just acknowledged my point about the problem with playing stock tanks in account rated SBMMs!  The sad thing is, you probably don't even realize it. Your comparison of a purple in a stock tank beating a red in a fully researched or OP tank is a benefit of Random MM! Where you don't get punished for playing stock or underpowered tanks. If you can still play better than the average player, you're still helping your team! BUT, under your SBMM the purple will be paired off against ANOTHER PURPLE!  For my concern to be 'babble' (as you put it), your statement would have to be: "A very good player in a stock tank will beat another very good player in a pimped tank 50% of the time." And you and I and everyone else knows that is pure BS!  That's why you used "a noob" in your example, but he's not pared off against a noob! He's paired off against another purple!  Thank you for acknowledging that SBMM sucks because of the issue I brought up! Not even you were foolish enough to pretend a purple in a stock can beat a purple in a good tank. That also means the match isn't balanced! And we're not talking a little bit off, we're talking purple in good tank gets to farm the reds and the stock purple! Thank you, thank you, thank you! SBMM sucks. You heard it here from SimplyPzB2! 

DeviouslyCursed:  You can't just look at 'half' the equation. You can't, on one hand cry about getting worse teams, but on the other hand not cry about some people being gifted good teammates and others getting shafted with reds. Have you not noticed I'm frequently using your own words and rationalizations against you? Do you not realize that I can do this and it makes perfect sense because there are pluses and minus to both sides, and which one is better depends on how you subjectively weight the pluses and minuses for each MM?   

DeviouslyCursed:  Yes, it can and does.  

DeviouslyCursed:  And to make those teams fair, you have to punish good players, and reward bad ones. 

DeviouslyCursed:  I'm not using half and half. I'm using all under one, and all under the other. And that's exactly how it works. Using your example   teammates  team 1           team 2purple           2                    3red               12                  11 Which teammates are demonstrably worse? What if this happens 6 times? under SBMMteammates  team 1           team 2purple           12                  18red                72                  66 One set of teammates is clearly better. Why is one player punished with worse teammates?These sets of teammates are not equal, and this is not fair. under Random MMteammates  team 1           team 2purple           15                  15red                69                  69 The 2 players are treated equally and fairly, neither gets a built in bonus due to MMGranted, small sample size it generally won't be perfect, but over time, yes, they are the same. Any advantage a player gets from the Random MM, they have EARNED with solid play, and contributing to their team's victory.Under SBMM less skilled player are GIVEN better teammates, and good players are PENALIZED with worse teammates, all so some people will stop crying about some unbalanced games.
