if you want eternal fire and water the easy way on Level 80 don't got to wintergrasp - the droprate is low, the mobs are high level and the respanwrate sucks. Go to borean tundra at around 48/13. Shitload of water and fire elementals around Level 68-70, droprate is around 1 crytsal / 2 mobs. Can be killed very very easy and respawn very fast. Hey, a few steps from there you can get eternal air, too...check out 44/10.
Well, it's more a tip than a guide.
