Also, keep in mind that luck is…well, luck. I didn’t get anything good for MONTHS on end. Slogged through levels 1-250 without any legendaries and was forced into using slow stuff like Rock Worm teams. I was nearly ready to just quit the game and then…
Mab happened. 
I was lucky enough to get her first day. She literally kept me in the game. After I got my second not much later, the game became a breeze and fun again. Since then, my luck has been exponentially better, while the past few months have been ridiculously lucky. I got Ra from like 10 guild seals. Last legendary? ONE glory chest. Our guild got Death from Legendary Task. Wulf took me like 20 glory. Got Draak from first 20 gem keys. Got 2 Krys dragons with something like 10 seals and 10 glory. And on, and on…
That said, I’m probably due for a luck swing, so it’s a good thing that I’m a hoarder. 
Everyone’s day will come…or go. Some will win, some will lose, some are born to sing the blues…
