One thing you should keep in mind after hitting lvl 50, is that reputation with Argent dawn can be a pain to get, so it might be a good idea to start grinding a bit in western/eastern plague lands, the latter at a higher lvl since it is a tough place to grind. Make sure you do not turn in the stones you get before reaching 6000/12000 honored reputation, because after you reach that point you will no longer get reputation for killing mobs, only by killing bosses and turning in stones… So you’ll get more out of it if you save your stones until you reach that point!
50-53: Nagas at the beach in Azshara, they die relatively quick due to their low armor/hp, just as any other naga in the world. Unfortunately they also drop as bad as all the other nagas, the silver is alright, but that’s about it, Unless ur lucky enough to find a golden pearl in one of the clams they drop. A good place to go if the satyrs are taken and u don’t feel like wasting your trip to Azshara.
50-53: Another option is satyrs in Ashaera, these are 51-53, but die so quick they can easily be grinded at lvl 50. I did this, combined with searing gorge and the cactus guys, just because some lvl 60 is always on the satyrs, and there isn't enough for 2! The fact that they drop Felcloth and traveller’s backpacks and cards for the faire is just a nice bonus.
51-53: Sorrow hill in western plague lands, some people like this place although I don’t hink it’s very good, due to the fact that there’s no casters. It’s all melee mobs, and they don’t drop very fast. If u want rep with Argent dawn however, this may be a good place to start. Good runecloth/silver drops and Librams have a decent chance of dropping here as well.
52-53: If u haven’t done them at an earlier state, the quests in Un’goro would be excellent here… Even if u did do some quests earlier, u can’t have done them all cause there’s a lot of 52-55 quests which are almost impossible at lower lvls unless u go with a group ?
53-55: The blood elves in Ashaera die really fast… They’re the same lvl as the satyrs, however they all do this nasty AoE which can get a bit too much if ur not high enough lvl… And they’re placed kind of tight some places, which inevitable makes u aggro one too many… However still very good to grind, they drop a lot of runecloth and silver as well, being humanoids and all.
54-57: Ghosts by the lake in Winterspring, these are a little tricky for a 54, due to the DoT the give u, which prevents u in bandaging, but still good to grind! These can be grinded all the way to 60, I’ve seen it done and it works fine… Although there are better places after 57…
55-57: Furlbogs just south of the entrance to winterspring. Decent amount of hp/armor and throw faerie fire on u, but there’s good things aboiut them as well… Good silver drops, good chance of blue drops, a chest with guaranteed green item (And often healing potions) and everyones favourite potion: Winterfall firewater drop pretty often from them, although this should change in patch 1.9 according to the patchnotes. Give reputation with the timbermaw faction as well each time you kill one, if you’re interested in that.
56-60: The birds in Deadwind pass, These are very good to grind, they die relatively fast, and drop very good vendortrash… The only downside is that they hit rather hard and put rend on u all the time which makes it almost impossible to start with an ambush… But if u use swords that won’t be a problem.
There are also very often other people grinding on these, and to be honest there’s just not enough for 2…
57-60: Yetis in Winterspring are very popular to grind, there’re tons of them and can be skinned for thick/rugged leather, they also drop silver… They do however have a lot of health points, which makes them a bit harder to kill, but if ur saving for ur epic mount, this will be a good place to get some good xp and some steady gold flowing…
58-60: The ogres in Deadwind pass, very good, just like all other ogres they die pretty fast… The amount of runecloth they drop is just unbelievable.
This IS a tasty burger!
