Why are young status players allowed to kill legendaries?
In the final game, there will be an entire planet without any PVP to begin with; all characters on that planet will have this same protection status.
As such, I don't see how it matters that the patched-in placeholder PVP system, which is likely to remain similar on final Syndesia with respect to legendary monsters, has this problem. Nobody will bother with it once they can just use Arboreus.
without dedicated pvp. the invasion will force a limited amount of pvp.
unless it's been changed.
