It would be good if riot implement a new mission call read the patch note?
They could grant maybe a bit of blue shard or even better a box shard. Maybe for each 6 box shard you get a key and a box. As a player you can get 3 (4 at max box at year so it wouldn't be dramatic) I fell like make it a mission would make a bit more people to watch the patch note. You can just add a check list box at the end of the patch note of the client or the website (require to log in).
