Full loot PvP games are supposed to be 'toxic' to some extent; that's part of the fun... BUT, the problem is that rather than deal with potentially limitless toxicity/grief with impossible odds(for example, you can't even compete ON PAPER because of the skill system day 1, let alone in terms of wealth/gear/player-skill), most people will just stop playing the game. Thus, before long, you end up with a majority of toxic 'I'm the alpha male look at my huge e-peen' folks... It then snowballs from there, as the ratio of d-bags to decents grows higher and higher. For this reason, sensible mitigations are essential for the success of a full-loot PvP game. That is why the whole PK mechanic (Murdercount & timer/blue-grey-red flags/regional reputations/guards) that operates under the hood of MO2 absolutely needs a major overhaul or complete rework if the game is ever going to succeed. Having longer res walks & less towns is not a fun consequence for being a red, and 'murdercount' & timers does not provide new-players with any recourse to being slaughtered like dogs.
The 'realism' argument re: having no recourse as a new player, firstly, isn't fun and, secondly, isn't actually philosophically realistic from a social standpoint. This is because, in real life people have real consequences and either learn to act in acceptable ways, or deal with being shunned/jailed/dealt-with in some way, by the rest of society. Whereas, in a game, there are no real consequences except that people will just get sick of dealing with griefers and stop playing said game, as the amount of enjoyment they get is outweighed by the anguish of having to deal with tiresome smoothbrained-fuckwads the entire time. You will never be able to get the kinds of inherent tribal affiliations that exist in real life, completely implicitly, to exist implicitly within a video-game. People in an MMO have no intrinsic relationship except where made explicit by a mechanic.
If you enter a game like MO2 with nobody ready to help, you are completely helpless and the game offers no real recourse in way of starter guilds, or actual social mechanics that might give you some recourse. Instead, the majority of people seem to promote misconduct, and don't care about the long-term wellbeing of the game as long as they can 'do whatever they want', at an extreme advantage (complete character build/wealth/guilds etc) because 'that's the point of the game'. The point of the game is an immersive fantasy world with full loot PvP, but the point of the game is not griefing helpless new players, and, if it is, then the game frankly is no good and deserves to die. People who take this line of thought are basically just being spoiled over-entitled brats, and SV should not listen to them if they want the game to succeed.
