And that, my friends, is proof negative that the Lucky Boxes ought to be renamed Unlucky Boxes. I ain't touching a single one of them. You want an item? Go after it as a single option if available. If not, I guess you'll have to keep hunting mobs until you get it as a drop, assuming it drops at all. I'm a minimal spender, since I think it's strange to spend real money on virtual items, but I know the temptation is still there (like with the Unsealer).
Speaking of the Lingerie Unsealer, has anyone else begun to suspect, as I have, that it is not actually in the Loot Box? After a month of playing I haven't gotten close, nor have I gotten an EXP Booster -- and then with the Star Wars tie-in the announcement says they will add the EXP Booster to the Loot Box. That's when I got really suspicious.
