Where to Level?
There are two methods you can use to level (or a mixture of both). You can quest, or you can instance grind. Both methods can get you and your friend to 60 in under 2 days of /played time.
Questing – This method only requires the Veteran and Recruit to party together and do quests together. You can easily skip any group quests that require more than 2 people because the xp from all the other quests more than compensates for skipping. At times, this method can be a little slower than instances but other times it can be greatly faster.
Alliance
1-20 – If both accounts have upgraded to BC then I recommend the Draenei lands of Azuremyst and Bloodmyst. These areas have the best concentration of quests with minimal traveling and by far the best leveling greens for a starting area. If one or both of the accounts do not have BC then the second best area would be the Human lands of Elwynn Forest and Westfall.
20-30 – Quest in Redridge Mountains then Duskwood.
30-40 – Stranglethorn Vale
40-50 – Swamp of Sorrows then Felwood
50-60 – Winterspring then Western Plaguelands then Eastern Plaguelands if needed.
Horde
1-20 – If both accounts have upgraded to BC then I recommend the Blood Elf lands of Eversong Woods and Ghostlands. These areas have the best concentration of quests with minimal traveling and by far the best leveling greens for a starting area. If one or both of the accounts do not have BC then the second best area would be the Undead lands of Tirisfal Glades and Silverpine Forest.
20-30 – Quest in Hillsbrad Foothills then Arathi Highlands.
30-40 – Stranglethorn Vale
40-50 – Swamp of Sorrows then Felwood
50-60 – Winterspring then Western Plaguelands then Eastern Plaguelands if needed.
Instances – This method requires hours of clearing the same instance over and over until you’re high enough level for the next instance. This also requires having a high-level character willing to run the Recruit and Veteran accounts thru these instances. This is the fastest method of leveling but can also sometimes be very tedious and boring.
