With recent rewards, people who play by spending their fortunes were the ones who received them.
Use case: People who already above 4500 were shorted to around 3500s at the start of tourney. This 3000-3500 trophy level is the place where we find many people who are trying to climb up the arena without spending a penny. Now that higher leveled people in the same range, it would be nightmare to win a single match for people without VIP or buying.
Anyways at the end, higher leveled people who got uniques/overleveled legendaries will easily move up the arena by crushing others and end up above the threshold to win the rewards.
Thus people who didn’t spend a penny would end up with literally nothing. And they would bag some losses and go down the arenas. Good game mechanics tho.
