Would like to see at least one Pro item in each Pro chest. While it is appreciated to receive the large quantities of pearls, pet food, and even crystals on occasion but the whole point for me to play Pro League is for Pro items.
May not be as important to higher level players as they earn enough crystals to buy whatever they want. But for lower level players we have to play many leagues to even attain a Pro item and many more to receive a Pro pal. May even want to do this based on hero level. Guaranteed Pro item up to a certain hero level and then less of chance for Pro item with high levels.
