I have come to believe that the fight temple is the worst of all of the temples. In order to do well in the standings you must grind non-stop on the shortest missions for the entire week while not even bothering to look at skill or timed missions or even the map once I have found my daily party ticket.
I did not start playing this game to click every 3 or 4 minutes with no thought for an entire week. Please do not do this temple again or at least for a very long time or you will lose many players due to sheer boredom.
Also, developer take note, diamond spending is even less during this temple as many of us are letting our missions boosters lapse just so we can do 5 minute missions instead of 3 to use up our energy and get on with our lives.
