Me and my sister just opened up a new co-op and since she is not at level 33 yet she can't play. Right now I am the top contributor in the boat race, obviously as I am the only playing . In the last co-op I was in the leader would use tons of keys to ENSURE he was the top contributor (it got worse when I was actually top contributor once, he freaked out and cheated a lot which led to me leaving the co-op) so, I've never been top contributor and I am wondering what the top contributor gets in the chest?
Like is it that good of items for my previous co-op leader to use 100s of keys just to beat everyone? Just really curious what is generally in it!
