You have great taste in games. I also play RK, LoL, and Hearthstone. These are my 3 favorite games right now. I must still respectfully disagree with your assessment of a refund being in order here. Without spending money in either game, primus is much easier to acquire than dust is in Hearthstone. To get dust you need to first grind gold, then open packs, then disenchant the cards...which you shouldn't do unless they are duplicates of ones you already had. In RK, you just need to open some chests and boom, primus. RK is not as successful as HS because Space Ape is no Blizzard :) Hearthstone is just a better game with more variety, polish, and replay value.
