The Conventional success in Wild Christmas in Tellville seems to be rigged to require diamonds
The first page description is:
0 of 1 times successfully participated at the Christmas convention.
I just ran through it did shows for 3 hours (yeah free xp & money so not all bad). However the item did not clear. Of course I got a failed event since there is only 1 success at the convention. Meaning the successfully participated means get the Success result from the convention.
Since the other four items can be completed playing the game normally why is the convention so restrictive?
There can only be 1 "success" in each convention regardless if diamonds are spent or not. Based on the schedule there will only be 6 more players that can get the skill point reward from that event. Everyone else will need to spend diamonds. Granted the winner of the event is usually the one that spend the most diamonds but that would be nitpicking.
