I would ask for adding clans.
In the clan, members could give DNA, often 50DNA / 6 hours, rare- 30DNA / 6h, epic-20DNA / week, legendary- 10DNA / 2 weeks and unique 5DNA / month.
Clan Wars give different incubators, for example you need to get some of these battle points in the arenas and expect some progress towards the incubator.
People who support my idea direct my heart to the future creators.
