in terms of the opt newbie pk immunity thing, this is a double edged sword.
on one side, i completely agree. idealistically there should be some sort of protection for new players to learn the ropes, explore, level, rank and do all the stuff that is fun while they learn about arctic and develop into more seasoned players.
conversely, at the top end of arctic many desperate players who seek nothing but to "win the game" by killing whoever they deem their enemy are always trying to find loopholes, including bending and breaking the rules to get any advantage they can to scavenge a win. these people would quickly identify that this pk immunity is a very effective method to level up "unknown pkillers" with absolute immunity. furthermore, players who are involved in pk who are not able to push their enemies off and load their decayed items could use this immunity to zone without fear of death on those no-pk type characters.
tl:dr - idealistically it'd be great if we had a pk immunity option for newbies, but there's way too many assholes who don't care about the game in general and just want to win who would abuse it in a desperate attempt to "win"
