Ya agree with most of what you said RHat, obvious situations in which you know what you could do will kill you. I feel is at that point player choice. If it's quite obvious for instance hearing what sounds like a rapid fire grenade launcher somewhere in the vicinity and then seeing something strong enough to punch in a reinforced steel door that was the direction you were trying to head in, is a clue. Might have you thinking about running, but what about that guy who runs through said door to see whats on the other side, while grenades are firing out of a belt feed grenade launcher in the very door way he wants to run through. I think I've repeatedly stated that directly killing a PC without choices without precursor knowledge, the possible intention to kill a PC just cause such as dropping grenades, snipers ect,. is not what I'm talking about and not really what the thread was about.
I probably would say hey that will probably get you killed to the player, a full automatic belt feed grenade launcher, that just another word for death chummer. Would I stop him beyond that, no. If he believes he can make it good luck. I am not a person who will beyond clues, hints, and even verbal warnings will not FORCE a player to not do the wrong thing. It's always the players choice. The fact is it happens how many players can survive a HE that lands by their feet, especially if they get a really poor roll or even worse a critical glitch. Not to to many. It's just the fact of the game that there are dangerous situations that even without precursory knowledge or the valiant attention of the PC has resulted in an untimely death, for instance an NPC using a HE grenade as normal. However that's what burning edge is for. As far as I'm concerned in SR5 it's EXTREMELY hard to die without a doubt. The original thread was about how people out there apply various amount of damage and/or perma damage. It is in the SR5 book. It doesn't have a section it's under various areas of the book. For instance repairing drones, weapons, armor, cyberware. Even burning an edge says that there are permanent effects. For instance you were laying down in your coffin hotel room and started playing with a grenade. The next thing you know you have a lubed grenade in your rectum. You survived....somehow. However you are EFFECTED, what that effect is, is up to the GM it seems most just don't bother however. These examples are littered throughout the book showing the ingrained dangerous nature of SR. I don't remember SR3 having edge, it's been a while but 1, 2, and 3, were fairly finite in deaths. SR5 has such a high level of reprieve, I'm not quite sure you can call it all that dangerous any more.
As far as character change, it's a choice, an option. Accept death as it is or cling on with what you can. I'm not sure offering an alternative can really be considered a negative. The rules above state that surgery is possible in every case including disfigurement.
Also ya it's hard to follow what I'm saying because on one hand I'm like death is common, and then everyone assumes OMG he's a player assassin. So the other half of the time I'm trying to convince everyone no I'm not a mass murderer and that players should have the chance to live. So ya I see why your confused. I'm trying to take both stands aka a middle ground while being shot from both sides.
I don't see anything wrong with a one armed shadowrunner, he just gained distinct style and a new nickname One armed bandit. He just became a street legend, people will wonder what happened to the great one armed bandit after he gets his other arm back. It's not like a runner can't put up for a used or cheap cyberarm till they get enough money together. Seems like prime motivation to run. It's also not like he's going to get his arm blown off every single run. Otherwise johnny needs a better seamstress.
