Started playing this a week ago, fallen quite in love with it. It's not iap heavy to win, I haven't spent a single cent to play and I'm ranked in the top 100 of the server I'm on. It's got some good dynamics, you can not only upgrade your character but all their equipments and they give loads of free booster packs daily! Also daily clan wars! Come join me!

Use that code on that server and you'll get a good head start!
My ign is FishTurtle so friend me if you need any help or ask in this thread!
