I love the contests because they give me a reason to level up/promote etc my less powerful heroes.
I miss the hilarious descriptions and would really like a return to those.
Feedback does register because we now get this feedback opportunity after the contest, not before as previously done.
The tier requirements are too high for me to get beyond tier three now but at present for me, levelling up my heroes is more important. I do understand the frustrations of others.
Keep the contests coming, maybe with more stamina or diamonds as tier prizes.
