Separated rankings (not battles) for players with special dragon, meta team, family team, and random team. You don't need to input rewards here. It's just for motivation, and we want to see who is the best among the same set of dragons. The problem here is that we can always change dragons. I think, it will not be so accurate. But, if unless it's not changed based on the category, still include them but if it changes, I think you should not include them in the separated ranks.
