Firstly, this post really annoyed me with what I assume to be you calling anyone better than you a smurf. If you don't know these common things are you even ready for mg? There is a different skillset observed in different ranks because they are just better than lesser ranks. The playstyle changes as people get better but its more of a case of silvers and novas just sucking, mgs rely on aim and have no gamesense and after dmg you actually get a decent quality game with good players and teamplay.
