Just a thought I had about comebacks and making the game a bit more fun.
Make the allied base health crystal both heal allied demigods, and damage enemy demigods for a simple negative amount as it heals.
Wouldmake the enemy think twice about having to come into range of the crystal and citadel (since most maps have them near the other), and for them to haveto be powerful enough in levels and creeps to take down the citadel.
Discussion?
