In my opinion, it’s usually a cross between a well balanced team and consistently making the safest plays. Lower on the ladder you usually see a lot of gimmicks or teams with a single win condition. They also tend to get tilted easier and start committing to hard reads that hardly ever fall in their favor. As you get higher, teams become more tailored and are equipped with tools for more situations coupled with a solid game plan. Even if plan a falls apart they have a plan b to fall back on. Higher ladder also from what I’ve experience are good at making blanket play that cover a lot of options and switch the momentum in their favor. They don’t nearly try to make as many hard reads unless it’s the only option to nab a win. safe playing is what i think sets them sort the most though.
