A newbie training ground would be nice. I've thrown my support behind this idea before. But not the temple of trials. We're not the chosen ones in this game. We're just regular vault dwelling peoples who got kicked out on our asses (actually if you read the help file, FOnline is a simulation and we're still in the vaults pretending).
No matter what kind of newbie area were to be put in the game, the biggest thing about it is that we should NOT be allowed back in once we leave. That would prevent people griefing the noobs before they're prepared to accept the fact that the wasteland is harsh. Let them leave the safety of the nest before they get killed the first time (can't you see people camping outside of the newbie training grounds? I can see myself hunting these foul noobkillers like so many vermin)
