These sites are tremendously useful, almost always. True, they only help with globals that you're throwing up at low cost (but that's not that crazy a situation... In many competitive games, people don't have huge piles of gems just sitting around) but they also help with all other rituals. Finding one of these sites can change your game more than pretty much anything else; only sites that give you amazing things to recruit (wizards, etc.) can compete. Even spells that aren't very compelling ordinarily suddenly become a bargain when they're 40% discounted...
