Wrong. My neck and second Ring are from Klaxxi and Golden lotus exalted. They are essentially free epics which saved me 2500 valor points which i could spend on other stuff.
Both of them are FAR FAR better itemized than MSV normal items so they are quite mandatory.
Next time try to inform yourself before you spout out "casual" nonsense.
You're still wrong. You don't "need" them. You "need" air, food, water.
You "want" them, which means you're taking the option to get them. They're "mandatory" because of your personal/guild objectives, not because if you don't get them you will die. You will survive regardless of your actions. Therefore, you're doing them because you want to, not because you have to.
