well I think their should be somthing to protect long miners but I am scared real pvpers might try aand take advantage maybe ccp should make the mineing ships harder for pvpers to catch esspicaly the noob ones like the venture
the venture has a built-in warpcore-stabilizer and there is d-scan and local to keep you informed about possible threats. if someone plays EVE, he should at least be willing, to use these instruments to protect himself.
nobody can force you to shoot back, although it is way more fun than running away.
i really do not think, there should be something like this in game, that prevents you from PvP.
the possibility to be shot at in any moment, is what makes the game interesting.
if you want to farm materials without being harmed, i am sure there are a lot of games that will provide you with that experience
