I know this has been said before, but it was a while ago and the thread has been locked, but I wanted to chime in and say that the Pirate Legend Weapons only be accessible to Arena players is kinda lame.
Someone did point out and say that other factions have things that are unique to them, which is a valid point... but I try to avoid PvP in Adventure when I can, and Arena never really appealed to me... and all the early year 1 Pirate Legends got there without ever setting foot in the arena.
Also, every time I have tried to actually get into the Arena, I get stuck in the lobby for an incredible amout of time, which makes it even a longer grind.
