Did they change bot hunters?

AFAIC bots used to only consist of 4 hunters: Strike, Ghost, Felix and Celeste. But I've seen other hunters behaved exactly like bots recently in duos, did they change it?

I saw a post the other day saying how we want bots easier to be spotted (like different skin colors), but if now every hunter could be bots that's like exactly opposite of what we want to see.
