"since you only play ror let me give an ror example:
https://www.warzone.com/MultiPlayer?GameID=15593757. Clustering can be great if done right. My clustering almost won us the game despite the fact that the other team consisted of much much much better players than my team (I had randoms, they had a set team - to see how poor my team was just watch egypt..)."
Hey, there I am. :D
Yes clustering the way you do it can work sometimes, but the type of clustering that most players do is completely nonstrategic nonsense clustering with no real forethought and planning behind it. 90 style clustering however can work, but it's a bit gimmicky and the level of reward depends on a multitude of factors.
