keep in mind, if you play solo queue, 99% of games, you will have ppl on your team who are too stupid to check the map at the start of the round and go with the right number of ppl to the right site. on train you will play with ppl who go 2 B every round even though enemies have been taking A for the past 5 rounds in a row. you will play with ppl who randomly stack 3 ppl B or 4 A on Mirage or D2 without saying anything for no reason. playing with the same ppl in the same positions every game is a huge advantage. it doesnt mean you cant be dynamic. you can react to what opponents are doing. you can also have structure in your reactions. if enemies push a certain spot a lot and your team cant hold it, put an extra player there, or play further back or forward. as long as you do that consistently, it will be something you can build on.
its impossible to have any structure playing with random people who you cant trust to understand the fundamentals of the game. with random ppl, you need way more aim skill and way more gamesense to compete at a certain rank, than if you play with ppl you know. due to that lack of structure. thats why i called it a short cut. you dont have to be any better, to play with more structure.
