They give the games legs and allow for the next generation to share the multiplayer experience long after the severs go down. I honestly wish all multiplayer games had bots on some level because once the severs go down you are looking at a expensive paper weight.
We know Apex Legends doesn’t have bots and adding them would be pointless. It would defeat the whole purpose of the game.
I miss bots, and wish they'd make a comeback. Games as a whole would benefit from developers spending time building better and more advanced AI.
