The problem with doing things like nerfing fusion/fragment events, tons of free legendary champions, truckloads of free energy, etc is everyone will get everything they want out of the game quickly and stop playing. :-) You have to carefully balance challenges with rewards and engaging longterm gameplay. Personally I think the best thing the devs can do right now for the longterm health of the game is to come up with content and play modes that encourage us to use more of our champions in creative ways.

 I do agree the book situation is out of balance. They've added more ways to get books to the game than it originally had but a lot of it is based off 1 time rewards and it would have been better if there was a way to consistently farm them at a rate that they were obtainable but as suggested above not so easy that it hurts the game. Perhaps we'll get a dungeon for books some day, until then NM/UNM Clan Boss is the best we have.

While you're at it, how about giving me a new car? Could use one of those too.
