Fact 1 : I don't buy any random box, and now have 13000 CC piled from monthly fees since the beginning of F2P
Fact 2 : I might be enclined to spend some coins if some of the boxes' content were avaliable to direct purchase, even if it costs more than the actual boxes.
Box costs 450 CC, and contains multiple items.
A single "average" (silver symbol) item could be purchased directly for 600 CC
A single "rare" (gold symbol) item could be purchased directly for 900 CC.
yup like that the boxes in Tera are 330 each, the outfits by themselves are 880-1048 basically more than buying three boxes
