What I am about to post is so infinitely obvious that even a closed door that needs to be opened in order to get into the next room is less obvious, but here goes anyways.
Why would I bother spending and competing in any event at present with the piss poor quality of prizes that are on offer? NONE
Why would I grind out leagues if the prizes are just utterly terrible? NONE
There is no desire for me to compete or to push the extra mile because you, Scopely, have zero clue as to what we the player-base want.
Make simple changes and your revenue will increase… it really is obvious.
