This depends on the hero the player is playing a Naga will be more focused on farming very efficienty while taking a few kills of those who try to interrupt. A Slark will be more focused on hunting all over the map. 10k enemies do allow efficient farming because they are also playing against 10k players, in general if its a 50/50 game both carries know very well just based on their map awareness where the enemy is and to which extent they can farm camps or waves, they also won't get a free lane. In 1k they will 1. Get a free lane and multiple kills so they are going to be able to farm way more freely earlier. 2. The enemies are not even gonna try to stop them a lot of times or they will just feed/fuck up the attempt to stop them.
