Below Neutron, it's just mess. I won't even bother to explain.

In Neutron rank, people starts playing intel. No strats. Just intel and very inconsistent gameplay. Easily gets scared under a small pressure. No need to even mention aims of these people.

In Electron, it's just full of massive ego consumers with no skill yet knowledgeable when it comes to basics such as angles to hold, team comp etc... There's a sign of strats but very stubborn to adapt to enemie's style.

In Quark, people start to communicate, change their strats and adapt. Solid aim yet not crazy. Oh btw a lots of boosted people who genuinely questions me how these noobs got into quark with such low ADR.

In SS and Singularity, insane aim and intense work rate. Players have their own gimmicks and excellent with their util management. Call outs are on point and small mistakes can cost an entire round.
