Its a system that allows people with very little to no mith to buy some for spells so that they can have an even playing field in war, and manage to war to earn more so that they can buy the new items and hit evenly in war. Have a look in the news section for the devs latest Estoc's threads for news on it.
So I've been trying & trying to retrieve a crystal or two that's "randomly" awarded when redoing the crystal dropping quests. Is the crystal being awarded randomly? Or very rarely?
I know the devs did away with xtal farming quests after resets, but I don't know if they did away with the ever so random drop. That's a good question.
