A proposed idea is to alter the moon destruction formula to a one that is better suited to the gameplay of current times, reducing the number of deathstars required to pop ruby moons, whilst still maintaining a considerable number for the popping of non-ruby moons,
A more linear formula would be considered a decent solution to this problem...

The current MD formula is:

Moon Destruction Chance = (100-sqrt(moonsize))*sqrt(number of deathstars)

An alternate formula is welcome in this topic or example moon sizes and rip numbers for destruction
