please make the next event shop have full keys

i really think that the next event shop should have an option to buy a full key, not only key fragments. for people that have a lot of chests and earn a lot of tokens throughout the event, they should be able to easily purchase a full key at 30 tokens instead of every individual fragment of a key at 10. Even after you purchase them all, you then have to take the time to craft them! its a very annoying process that i think should have been addressed at the very beginning of these events.
