With the challenge system as it is, there is a major problem with AFK and people quitting. In 4/5 someone quit, it would find a replacement, now it’s just a bot.
Personally, I would rather it be like 3 where nobody can replace at this point over an idiot bot that can’t do anything useful.
I’ve seen a bot grab a flag and run straight at the enemy team, stand there and get shot, and do it over and over until he gets that flag back.
Maybe bump the AI to ODST at minimum? Or just let people join.
