Forgive me if this is in the wrong section but I really wasn't sure where else to put it. This isn't really a guide, more of a tip I thought I'd share. I just found out about it now as I was leveling on my 48 hunter alt. In Feralas at 44,8 43,3 there are 2 quests, Fuel for the Zapping and Zapped giants, they both require you to kill giants and water elementals along the coasts. The water elementals are great for farming because they drop a TON of Enchanted Water - Item - World of Warcraft. I'm talking up to 4-5 stacks at a time. They are also squishy so they are very easy to kill. The mobs you will be farming are:
sea spray - Sea Spray - NPC - World of Warcraft
and
sea elemental - Sea Elemental - NPC - World of Warcraft
There are a bunch of them along the coasts and because they drop a lot of water at a time you wont have to worry about mana so you can easily blow all your mana killing them and make it up with the water they drop. This won't be useful to Warriors, Rogues, or Mages but all other mana using classes can really make use of this. On my 48 hunter I was able to blow right through these guys popping everything I had and still I ended up with 65 extra waters. They range from levels 46-49 and the xp they give at 48 ranges from 250-299.
