Daily and weekly tasks could be introduced, like Nyan Heroes, to encourage people to play because now those who have them are high in the ranking have no need to play because they can only lose. For example, in daily missions something like: Play 5 games with another player during Hapy Hour or defeat five different players (to avoid playing on multiple accounts), Earn at least 100 ELO ect. For completing these missions, there would be additional points on Zealy and it could activate players who are high in the ranking because they would not be able to wait calmly for others to catch up with them. I know it works because I played Nayan Heroes and if I wanted to stay high in the ranking, I had to be an active player and complete these tasks.
