Smaller clans often can run 8-12hr ebs. This causes a real issue for members who fall asleep during their second eb and can't collect their Legend Reward before it is reset on the new day. Those two free boxes for smalls make a much much bigger difference in growth and only gaining 1 box a day is a serious issue for smalls. My proposal is that where ebs finish and a player is active and has a current 'Complete an Epic Battle' legend, it should be automatically given/collected. That's all. (I'm an lb account so have no benefit for this. I just find it easier to type in forums on the computer and not a mobile phone where I loose all my typing when I accidentally hit one of the phone bottom buttons.)
It does do that though. If you complete a legend and the legend expires before you click to claim rewards, they get delivered to you anyways and you get a small notification in your newsfeed.
