Isn't it a loss to sell Lagerstroemia Star?

It's not a loss to sell Lagerstroemia Star. Purple star is worthless, mainly because no one will buy it. Purple star is only used before level 60. There are so many ways to upgrade now, and level 60 is only a matter of a while. No one can do the purple star mission. There are so many strange things to play and little experience. To sum up, Purple Star is worthless and can't be sold.
