I was using the IB situation to advocate for balanced matches. Nothing more. The soccer analogy seems inaccurate to you because you use only the Primera Division for your example. You have to use all of Spain football leagues for the example to work. See, the analogy is that the Destiny playerbase is basically all football clubs. That includes RM and Barca as well as your local amateur soccer club. For the system to work you need to sort all clubs into leagues, with the strongest clubs contesting for the title in Primera Division. Even though Barca, RM and Atletico are somewhat better than the other clubs in the Primera Division, they are still on kind of a level playing field. A perfect balance is admittedly impossible and that's not what I was trying to say. The point is that RM don't regularly play 2nd, 3rd or 4th league teams. Plus, even though there is probably thousands of soccer teams in Spain and dozends of leagues, every league still has its own structure of better and worse teams, showing just how big the skill spectrum is. Destiny is no different. SBMM granularily tries to sort players into brackets and lets them play eachother while constantly reevaluating their skill and resorting the brackets' players. This let's everyone gradually improve (at least if they want). I would definitely prefer that kind of system over something as random as CBMM, where some of my games are easy (and I learn nothing) and some are impossible (and I also learn nothing).
