Yeah so I keep hearing though I doubt I will reach the black knight any time soon lol.
To give you an idea of my doubles horde I have see below:
I don't plan on CRing and Skill Uping all my gold units just those I feel are important like Yuyu, Iris, Themis (even though she is one of the worse of princess's), Kerry and maybe Cyrus. But I wont rush to sell all my doubles at once because as it has been stated numerous times the RC trading post isn't going any where and I have plenty of time to work up those RC's.
Still I can afford to lose some of my golds, just not so eager to see my plats as I have Rachel as part of my main team and plan to CR and SU her.
