Why extremely rare event

I have spent money very poorly on this game. I won't say how much but it's more than most of you and more than a lot of people combined. I never bought Aurodium packs with any consistency maybe a few there a few here. To be perfectly frank, when you say that you haven't had an opportunity to farm rebels the answer is right in front of you. I have slowly farmed all of the characters available in arena, GW, and cantina over months and months. For you to complain tells me that you are relatively new to the game because you have invested in the characters that you saw you wanted or were powerful. Don't worry friend, you'll get there.
