I think that once you reached the top there is nothing to do.
Easy solutions to make it stress free and more interesting:
Leader being able to choose from 3 titans of different strenght
Spezial wars, new field aids, elements forbidden, 5stars forbidden (a bit like tournaments, for extra fun only forbidden for attackers), Velluria forbidden
etc etc like said a hundred times and no dev listens. Why? Because you/we paid them well just to reach boredom.
