I've been playing video games for over 30 years and I've probably spent more than $10,000 on games and consoles, extension packs, etc in that span. I have also spent money playing this game. Less than $100 total I'd guess... I honestly love the game and think it's the best mobile game I've ever played so congrats to everyone who's worked on it.
That being said, I'm not personally a fan of the casino style "a chance at" purchases. Some are I'm sure, you can get good stuff... I've seen the screenshots. The times I've spent are when you sell a package with guaranteed items. Mostly raid gear in shipments.
I know a lot of people that bought the rebel pack and honestly it was a great deal. The best part is you knew what you were buying. It was a very informed purchase. Can we get more offerings like that? I'd bet individual character packs would fly off the shelves if you'd guarantee what we were buying. The chance purchases raise frustration and discourage spending when you don't get the stuff you want.
Thanks for making a great game!
