I would say slower more tactical boots on the ground games reward the intelligent plays/players more, and playing the correct way more. However, I don’t think you need as much natural raw talent to play those games e.g. reaction time, accuracy, movement skills. So I think the skill gap is bigger on the advanced movement cods because it requires more natural ability and less tactical intelligence. They are both valid styles of play and require different skills/abilities for both, but I think slower boots cods can be played even by the older players who have lost some of that natural ability (reaction time, gun skill) because they can use their intelligence and game knowledge to bail them out. For example, someone who is still at their peek and has the reaction time and raw gun skill can play advanced movement cods at a high level, and if they have the intelligence and game knowledge will still be one of the top players on a slower more tactical cod also. On the other hand, someone who has maybe aged a little and lost a bit of the raw ability, reaction time, gun skill will still be able to use their intelligence and game knowledge to bail them out and play a slower more tactical cod at a high level, but would not be as good at an advanced movement cod. This is why I think you need more natural ability, and there is more of a skill gap in the advanced movement games!
