Strangely I've had great drops for the last few months and no sign of it stopping. Decided to keep a log - since 30th October (so 9 days) had 6 sacreds, 9 lego books, 3 voids and 3 epic books.
I had 1 sacred which gave me a crap Epic.
No Epic/lego Books.
No Upgrades.
I'm quitting this game because i'm not paying 60+$ to Book every champ i got.
Yeh I kept an informal log as well which is why I know it's three weeks since last Lego book. I have had 1 sacred in that time. Wierd how people seem to have luck in waves!. Oh well it will change eventually I guess, but it seems utterly pointless building champs when I am looking at 6 months to book one at this rate!
I've been playing this game for a while and I have many legendaries I simply won't use because I'm not willing to book (they aren't that game changing). I always keep about 10 stored in case I get that one amazing one that just needs it.
It kind of sucks, very much love to try new heros and new builds but the books are really what hold me back from doing so. Everything else is somewhat farmable.
