Support
Then only thing...Crystals are used to gain an advantage in a war. If everybody has two Extra crystals per week there is not really an advantage.
If this idea had been implemented I probably would've never quit. Great idea with outstanding support. Just goes to show how much the devs really care.
Still think this is a great idea, the current war system is clearly prioritizing the paying customers with no regard for those who can't buy xtals every day until they die from starvation...
