seriously. you are triggering me with all the threads you made and answers you put after people reply to them.
1-10 starting zone (usually its faster just to grind mobs, like spam kill them to hit 10. if you have 80 char alrdy, tag with lowbie, kill with 80)
10-20 i honestly just find a mage and ask him to port me to orgimmar, then i travel to barrens, but any zone fits rly - ghostlands/silverpine forest
18-25 stonetalon mountains, its very eazy zone to level due to most quests being nearby, must do quests that are between barrens/stonetalon mountains entrance(easy kill quests)
25-33(35) tousand needles - ez quests within small map.
33(35) - 43(45) Stranglethorn Vale - no matter what others say, yes it is one of those places that you will get ganked alot, but even then, its still faster to die 50 times and run to your corpse then level up, than avoiding it and wasting sht loads of time traveling to other places. if you see you are getting corpse camped, just aither try to ress and run away without being noticed or wait few mins and he will be on his way to search you. and dont bring ur main to booty bay, just pick up quests with lowbie as fast as possible, else you will get ganked becus u have 80 nearby.
if you hit 35-36 in thousand needles you can visit swamp of sorrows or badlands, i did quests everywhere and both zones are easy, just more traveling. so you can hit 45 there.
43-50(53) Tanaris - same as STV, lotsa ganking but easy quests and fast lvling.
after 49 you can go felwood, you wont meet much players there, rather easy quests, get to 54 there preferably.
54-58(60) - winterspring. its a good map, rather big but lotsa quests, i personally lvl there alot, but i dont rly like that map due to its quests, they used to be buggy back in my day, wich is alot of wasted time. but anyway, reaching 58 there is not a rocket science.
58(60)-62 Hellfire Peninsula - alot of easy quests, you could basicly grind just mobs till 60, alot of low hp mobs and give ALOT of xp compared to earlyer mobs. i always get flying mount to avoid ganking, thats why i get to 62 here, alo of easy quests.
62-64(65)- zangarmarsh - nothing much to say here, 1 camp full of quests right near entrance from hellfire to marsh.
from this point i always do this, go to nassigwary camp(Nagrand), do all the quests here, till i get achievement. then i fly to Nagrand arena, do those boosty quests, get my weapon, and bam, im 68 if not 69.
Northrend.
Back in a day when i was leveling characters 1by1, i could get myself in Borean to 75, then get myself to dalaran, take Zul'Drak arena quest, go to Zul'Drak arena, do the quest chain, get the achiev, and im 76 with like 50% exp.
76-80 Sholozar Basin - pretty straightforward, go to camp, take all quests there, do em, then go to middle lake, do some quests there till ur 78. Then find Gaya and finish things up.
Overall thats roughly 11-15hour lvling path, depending on your luck and experiance.
P.S yes, looks messed up and not rly well organized, im lazy to make it look appealing.
nor i think i should.
