提案/Suggestion
我認為讓好友加進好友任務時應該要有一個任務主人同意與否的機制，不然這種懶惰的小人只會愈加猖狂，破壞遊戲氣氛。
現状/Current Status
有一個人在我跟我的朋友兩個人解完第一次好友任務時，任務是打150隻大型魔物，此時只剩下8小時結束，然後這個人毫無徵兆的加進來，一隻魔物都不用打就領到了獎勵。
I think there is a minimum contribution to the quest in order to receive the rewards (not sure how much is needed though). But it is good to be able to remove people from the quest, in order to minimize such free-loader.
1 is the mininum contribution
