Everything is to hard to come by. Gold is rewarded very low and gems are rare. At first they toss stuff at you but quickly it slows down. The price to level up your stuff gets stupid expensive and only way is to buy the gold and gems. Winning gets you gold in double digits but you need 35000 to get level 5 to even unlock equipment to compete at all in the 4v4 with people who paid for gold. Your capped at 5 chests that take 2-12+ hours and you don't gain one unless you pay gems to open.
