Games with pvp safe players still complain either new player protection being too short (no matter how long it is) or getting pk'd right after the protection ended. They learn nothing about pvp while being under newb-protection and can't watch out when it ends. If the plan was to help nubs to gather enough equipment and stuff so that they could do better when they encounter a pk it wouldn't help since equipment aren't as effective as builds. Besides most pks carry good enough guns to kill anyone.
Not to mention newb protection would be used to shameless hq ore mining.
It's not meant as newbie protection, but more of a newbie training program to teach them the basics of the game.
They would be protected during the course of an event.
The few events I've been in all ended in PvP.
Once the event is over, so is their protection.
At the end of the event, they'll lose everything gathered during the event.
That way they can learn the basics of the game like trading with other players, marking people as friends or enemy, etc.
Nothing more, nothing less.
A PvP event for new players is also an option.
They will understand they don't stand a chance against a level 21 heavy gunner build.
