What would take elements to the next level, without changing a thing, would be an automated cycling tournament system as seen in Urban Rivals. The gameplay pales next to Elements, but the ability to constantly enter tournaments and win prizes is a huge attraction. People LOVE War, the weekly tournaments, etc etc... but it's hard to make time for the weekly and even harder to get involved with War. I have taken some time off from playing, but upon coming back, this is what I feel is most lacking in my current Elements experience.
Could start with Daily, or each 6 hours ... then go from there as people get addicted.
Thanks for reading,
