@Xinybaws Same reason when my main got TengoryuKarate from the Thank You Scroll Box, and then later on I made an alt and what did it give me? Well **** it gave me Hung Gar (Perm) so I do agree with you about one thing. I do get bored of my main sometimes so I go play on an alt account. But it always seems that the accounts that you don't use as much gets more luck on things than the account that you play the most.
If you had looked at the screen shot it tells you that he got it from the "Black Friday Box (Blue)" that they gave out just for being online for 1 hour.
