Sadly I dont have much good i can say about this contest.Only thing that looks interesting is the K King stones.
The tier prizes are poor. Ore is a terrible prize at the amounts given. I would argue that it is useful on first or second tier if giving 1 mil or more gold. Purple and orange chests are rubbish as been stated by many on many occasions. The other tier prizes meh.
More bazaar tolkens, stamina refills and diamonds mixed into prizes would be better.
Contest is also less interesting as the points given for fp/col/exp wins are not high enough to be impactful.
