When you get all the items from a Quest
there is no point in getting more wins than getting On the leaderboard. Getting this 100 and more wins should be more rewarding. For example you should get a shirt for winning for the first time, after winning for Lets say 10 times the shirt would upgrade in some way (maybe adding GT themed decorations around a goblin logo on the GT shirt). It could upgrade when u get 10, 25, 50, 100, 250 and a 1000 wins in a Quest.
