[Flamewrought Key] ,
[Reservoir Key] ,
[Auchenai Key] ,
[Warpforged Key] ,
[Key to the Arctraz ,
[Key of Time]
best way :
60~62 in hellfire , to unlock dungeon quest's u need to do almost all quests here and they are realy easy with good xp , if i dont mistake only 1 hellfire dungeon quest is in shadowmoon valley - so by this way u can have
[Flamewrought Key] for Hellfire citadel Hc's
62~63 or 64 Zangarmarsh , is good to know there are x2~3 facition rep for each facition (horde / ally) in zangarmarsh
and u only need to do quest's at Cenarion refuge for rep for
[Reservoir Key] for Coilfang Hc's , is better to dont wast ur time for other rep's at this point
63-64~66 u should go terrokar forest , before it , go and take shattrath quest's for lower city rep , but u'll recive enough rep for lower city by doing nm Auchindoun dungeons for
[Auchenai Key] , also is usefull to know most of quest's in outland which are not for specific rep , will giv u Lower city rep , it is kinda common rep
Dudu's dont forget to do chain quest to unlock "Raven Lord" boss for Epic mount "Anzo"
66~68 go Netherstorm , there will be 3~4 rep here too , but for
[Warpforged Key] u need Sha'tar Rep , best way to farm this rep is to do tempest keep nm dungeon's , Dont forget to do some quest from shattrath and netherstorm for
[Key to the Arctraz for 3rd dungeon in netherstorm
68~70 go Nagrand , there will be mostly Group quest's , just to reach 70
in additional there is 1 more key
[Key of Time] for Caverns of Time hc's , this key need some tip's
u cant do "The Black Morass" by Rdf w/o chain quest , it is kinda Attnue
there is a quest at entrance of Caverns of time By Dragon , it is not hard , first one is auto complete , second one is explore caverns of time with Friendly Npc , after it u have to do 1 quest in "old hillsbrad foothills" , remember u need to complete all quest inside of this dungeon , they are chain !
after u r done with this quest's , quest giver outside of instance will giv u a quest which lead u into "the Black Morass" , after u complete quest here , u'll have enough rep to buy
[Key of Time] , also u can Do "The Black Morass" By Rdf after it
At end , Do u need to do quest's in "Shadowmoon Valley" and "Blade's Edge Moutians" ?
i would say Dont do them for now , there will be quest's for other outland rep's but they are not neseccary at lunch of TBC
Also in "Lower City" there is a Daily Random Quest which will giv u x2 "Badge Of justice" and reputation
