The option to set the bot count to 50 disappeared from custom games lone fighters. Let it be a 25v25 or at least what it used to be, 20v20. Preferably players will join in and replace some of the bots but much fewer people are going to be interested in joining the game if they risk playing on an empty map so you’ll most likely just play an empty 10v10 vs bots as it is now.
As a side note, being able to add more than 20 players/bots on squad mode would be nice to have as well.
