Silvaring, your wrong on all counts. Play the game before critiquing how it plays. 1) blood vials are not always easy to come by. You can have 20 of them, each filling 25% of you bar. But when you are out exploring through a level, they get used up quickly as you make mistakes, get into trouble. Many enemies can kill you in a few hits, and their AI andmob tactics are strong. You will die, you will run out of blood vials when you are far from safety and bloodborne is as lethal as the souls games. 2) some groups early in the game can be lured, but it's more complex than that. Groups patrol. Some enemy hunt you down. Then there is other players to deal with. You can be luring one enemy at a time, only to have eight guys come up behind you and pinch you between two groups or get you trapped in a bind. 3) there is no encumberance, you move quickly. Movement not nerfed. The clothing and weapons you are using are all roughly similar. It's not the kind of game where you customize a big heavy or quick light character.
Bloodborne is an excellent game. I've played all of the souls series. This one is worthy with new twists. If you enjoy the previous games, you'll enjoy this one too.
