It is not for nothing that I wrote at once and exactly we need to get rid of ganking ?No it wouldn't. Ganking exists in every game with mixed PvE and PvP elements, even if the game has dedicated PvP zones. You could also argue even in some pure PvP games, because ganking is a valid form of gameplay. If you can name me a game where it doesn't exist I'd be surprised.
But if you ignore all this superfluous stuff about how people play the game, which you should because this is not the place for it, then your actual idea is a weapon that has no drawbacks (especially if you're not carrying cargo), that allows you to escape any situation. So even if you're about to die because you've just been interdicted by two Glaives and you know there's no chance of escape, you can just click this button and be taken to instant safety.
Accidentally fall out of Supercruise into the Jet Cone of a Neutron Star? Well you don't have to worry about trying to navigate your way out, or dying a slow death, just click the button and be taken to instant safety.
No dangers? No collateral damage to your ship? No restrictions on usage?
I've never played Fallout 76, but I've seen someone else play it. I asked him what about ganking? He did not understand me, and replied if someone comes running with a level much higher than him, he will just give him extra shmtoki and run away. When I told him how Elite is, he was surprised at how toxic our community is.
Even after destroying Titan and there people still manage to gank just to hurt others. I love Elite and I'm ashamed that ganking is considered normal gameplay here.
As for just saving, that's a good point and it's a real bad point.
I think the cost of a $10 million bomb would solve that problem. Then again the traveler won't be able to buy a second bomb.....
