This event's rewards are so stingy

Back into the dreaded section again.. lol 😔 Now I'm running out of coins lololol What kind of round event is this, where you have to collect the required amount first to win the duel and keep advancing rounds. You can even take a break in between. But it ends at round 9, Isn't the final reward too meager? 😔 I thought it was 1000 energy for a moment and got so excited.. But it was gone in a flash, and I escaped the merge swamp lol
