Yeah before the initial wipe I spent some bucks to open some packs since I couldn't resist lol Once the wipe happened they refunded you back with gold & now Ive been mostly using that for Arena's and getting packs that way. Works out, plus don't really mind spending some money on a game I play as much as this one.
Having fun with the game, always feel free to add me. :)
Anyone that opted in to the beta but still hasn't been sent a invite, be sure to check your whole inbox! For it to be in the promotions tab in gmail is a common one people miss. Since anyone that signed up prior to 12/16 should have received a invite now.
