50-60?

[Cypher]

Hi!
Right now I am level 49 and almost 50, 49 has been a pain and ready to get on to the big 5-0! Anyways, I was wondering if anyone has a nice zone that I could get from 50-60 ASAP at. I am not a tailor (Engineer FTW!) so I do not have to worry about gathering ingredients for Robe of the Void. Also maybe any quests that you might suggest? Thanks.

Well, you could have a look-see here for quests.

Just dinged 50 this morning, and usually I've spent my 50-55 in Azshara (ghosts, satyrs, nagas) and 55-60 in Winterspring (ghosts around lake, yetis).

Blasted lands
Great quest to do at around 54 is The Stones That Bind Us. After you complete it (7550 xp) , you walk 10' and turn in to another npc(3000 xp) then click on the chest that appears and receive 6000 xp and http://wow.allakhazam.com/item.html?witem=10659 16,550 xp! You can find the starting npc(his name is Fallen Hero of the Horde) at the entrance to Swamp of Sorrows when coming from blasted lands. He's just off the road on the right.

Lots of good quests in Felwood and later in winterspring

Also, the quest "Stealing knowledge" (horde only, I think) is worth mentioning. From Valormork in Azshara, you ride east for 2 minutes (into the ruins of something-something), pick up four tablets, and deliver them in UC, Org, TB and the archmage in Azshara, then deliver payment for the tablets to the original quest-giver. Somewhere around 25-30k xp and 4-5g for 20 minutes of work.

I dont' like levelling from 45 to 50 much, but 50 to 55 is great.

You can go to:
 Ongoro
  Better go with a fairly empty quest log, because there are aLOT of quests here..
  Don't forget your mithril casing for the Ami gorilla quest...

 WPL (western plague lands)
  There are alot of quests to be had here too, but you'd probably want a friend,
  preferrably a 60. The cauldron chain is great, there is also another nice chain
of three quests up past the logging camp.

 Burning Steppes
  Reasonable number of quests.

 Azshara
  Not to familiar with, but some decent grinding zones i'd say, especially for locks.Â
  Demonic Sac VW, then Enslave. ftw.

 Felwood
  You should be able to do some of these quests, and maybe come back in a few levels to do
  the rest. Once again, Demonic Sac VW, then Enslave a chunky demon for the win. I like
  the hellcallers up north...

 Winterspring
  This is more for 53+ but some quests here worth doing

 Mara(If you haven't done it already) then ST (sunken temple)Â
  These are basically the instances for your level; but you don't really need them.
