Many people don't like the fact that after event you have like 10 chests still remaining but you can't use them. Now I'm not saying that devs should make it so we can open them outside of events. I have a idea of how we can use more event chests inside the event... I think that along with whatever reward you get when opening chests, you should occasionally get a Chest token. These Chest tokens give you the opportunity to open another event chest without having to wait 24 hours. So when you receive a chest token along with a reward it should appear in your news feed. Then you can go to your profile, find the token on your items list and press it then press a button named redeem. After doing this you can go straight to marketplace, purchase another key and open another chest. I don't know if an idea like this has been suggested before, but if there has then I'm just confirming I thought this up myself Please if you think this idea can be improved,leave your ideas
