Here is some feedback regarding quests.
First of all, I love quests and would like for them to be a bit more frequent. That said, I’ve had problems with completing quests of the type “make X damage with character Y”, because damage hasn’t registered correctly. So I suppose that’s a bug report, though it worked most recently.
But, and here’s the reason I wanted to post: there are some quests that just feels forced. “select X reward in challenges Y times” - why? It’s not an accomplishment to choose gold or gems or gear. This feels forced and can create a negative experience. For instance I may feel forced to pick that low level reward of the correct type, rather than the high level reward I might have picked otherwise. This could just be “complete a number of X challenges”.
Also, “move character X a total of Y times” is not an accomplishment either. I feel forced to move and delay the action rather than attack or something else.
Other quests, like defeat 8 heroes, win 2 battles, perform 100 attacks, trigger an ability 50 times, gain 150 trophies, open 3 battle chests, they are more natural accomplishments.
Otherwise, just thanks for a fun game!
