Why are skins turned off in wasp + fire game mode event? Whats the point of having skins if you can´t use them in events?

This event would be good if you didnt make people go tankcoin broke . You sould win at least 4 score points for each battle to this event be balanced ,or at least have more missions with energy rewards .

10 hours have passed since the event ended, and I still didnt get my winner event rewards sadly ?
