You mean like in RE4? I don't think that would have worked either honestly. Imagine walking through the game with two characters on your ass... No thanks...
Give the game some slack man. It's still a 10.
Well, the problem with resi 4s followers is that they were on your ass even in safe zones. Let the characters be free during zones where there is no combat/ stealth. Otherwise keep them together or at least tactical in their movements.
It would totally suck if your ai partners could be attacked or killed but I also feel like they're not in any danger. Why do I need to escort Ellie if she can't die? She's invincible!!!
that last part about Ellie is me being sarcastic
