- AR has more recoil, harder to manage.
- Less spread - less randomness, more skill involved.
Whereas:
- SMG has less recoil, easier to manage.
- More spread - more randomness, less skill involved.
The difference is this, where as recoil can be controlled, spread is a factor that cannot be changed without pulse firing. Therefore just because someone uses an AR, it does not make them a n00b compared to someone using an SMG - if anything they are more skilled. Maybe now Elite you'll understand.
