What level are you btw?

I opened dozens each time and never got a good ninja... I don't think I've gotten a ninja period.

There was some su*ions that lower level players are more likely to get good stuff in such packs, to entice them to stay with the game and/or spend. So if you were on a newer server....

On my server, there are very very few player who gets the ninja, probably only one or two a month. It's a very old server where half the active people are 90.
