I was thinking about how Bots could be implemented so ;
A) games could populate faster

Reaction Time.
The Bot mech detects the player and fires in 1 second if Tier 1, 2 for Tier 2 and so on.
Like Turrets and the onslaught mode of tutorial map.
Solo players get bot and solo players
Groups get groups and bots.
Ask Epic for some help, the Bots in Fortnite are great fun.
