People saying they'd rather not have the game are bizarre. Yeah it won't be the exact same without From but what does it hurt to make it? It could turn out to be a good game. The only other alternative is to never have another Bloodborne game in this scenario. I'd rather they roll the dice and make one rather than never getting anything from that IP again. If the game is good, great. If the game is bad, then it's bad. Don't buy it. However it turns out, it doesn't impact the first one in any way. A bad sequel doesn't automatically make Bloodborne terrible. It also doesn't ruin your experience with the first game. I'd say it's better to have a chance at a good game than no game at all.
As for who would be the right fit, Team Ninja has come the closest with Nioh so give it to them and see what they come up with.
