I would like to say that the door block is too rude. why? It happend today. I was just walking around, then opened 1 door. My phone started ringing. The phone is in my other room so I just calmly walk pick up the phone. I end talking on the phone, and what happend? I'm dead! I was like wtf, but then looked thru the messages. I lost all my money! I was just about to buy new stuff! who the f*** was like:'' Hey that dude ain't moving, lets kill him and everybody gets what they want from him.'' why can't you just teleport??? huh?
Another idea - Blockers can be bypassed (you can go through them)
