High rolling has always been a thing, it's really just how unique every class became, with their own little unique gameplans tied to their hero powers and buddies. It's not the buddies fault that dong end games became more prevalent. Anyways before that other things were a problem, but the biggest problem to me was a lack of variety, options, routes you could take. Buddies solved that and unfortunately I don't think buddies will be back anytime soon, maybe a once a year thing. Personally I think they should be a staple.
