They've recently updated bot royale so that the player can choose the level of difficulty of the enemy bots, which happens to often take the form of more elaborate movement. But I have to say, you can still tell they're bots. The thing that really changes with level-of-difficulty is their aim. They used to hit nothing. Now you have to keep to cover, which is good because that's how a real game works, but is also annoying because one of the things I love about bot royale is knowing that I'll win pretty much no matter what.
Maybe it's time for Respawn to have the pubs bots kick it up a notch depending on... average skill of the lobby? Something along those lines.
