I think a new implemation would be a vortex wars lottery that happens once every week.
The basis if my idea is that if you log on to vortex wars (in other words get your daily vortex shards for logging on) 7 days in a week in a row that your name be put in a drawing of all the people that played 7 days in that week. The winner winning various prizes that differ every week.LIke 1000 vortexshards, 1 week premium, (non-boost races), +10 attack boost, +10 defense boost. a background ect.
I think that this would be a good implementation that would get more people to play more often.
