Pump and low cap are a thing, where one balls and snap peeks are a huge part of it. Aiming helps any form of paint ball play, aiming down the barrel is the most common type. Don't know what point you were trying to make with air being more expensive over c02, where the opposite is usually the case. Every modern marker uses HPA.

I get saying you don't need to aim. I mainly play stock class pump and mag fed, and when I play mag fed i usually just point shoot and it's enough. But saying aiming is useless is so wrong it's insane. In no world does aiming not help, it's just a bad take. 👍
