I thought that the champion rewarded a pool of shards that was distributed among the participants proportionally to their participation, but now with the chart and all the info, i understand this is not the case.
In that case, what affects the club champion's level? Since the BDSM update, champions have been incredibly hard to defeat and just not worth the trouble anymore, and i'm level 350, i can't imagine how rough it is for lower levels.
Most people in my club are around lvl 100 - 200 and they're all losing interest because at this rate, they'll never get enough shards anyways
