That's true, I mean I know the average skill level of a WC3 Dota pub was normally pretty low and all over the place. When I tried it for funzies about two years ago, it was like that. 3-4 couriers in base, my team was yelling at me for going Blink Dagger (or Kelen's Dagger rather) on Tinker instead of going straight for Scythe after BoTs and Soul Ring.
the meta back then was own courier for mid since you have to share units in the options to share the courier
and mid was static farming bottle crowing affair hahahaha
