I'm a big World of Warcraft player and thought I was pretty fast at leveling my Horde and Alliance characters have levelled (/played time below):
3 PVE Horde characters (Priest, Warlock and Rogue) and on average they took around 8 days played time to level 1-85.
2 PVE Alliance characters (Druid and Warrior) and on average they took around 8-1/2 days played time to level 1-85.
4 PVP Horde characters (Warrior, Warlock, Priest and Hunter) and they took around 10 days each to level 1-85.
And 2 PVP Alliance characters (Druid and Priest) and they took roughly 11 days to to level 1-80.
A good World of Warcraft friend of mine has been raving about two WOW leveling guides which he bought, one Alliance one Horde. The authors of which apparently leveled their Hunters in 4 1/2 days which is really impressive (if true).
Since I plan to have at least one of every WOW character on both a PVP and a PVE server I decided to try out the leveling guides for myself.
I first bought Brian Kopp’s 1-85 leveling ebook for $35 and it's brilliant!! Each section of the guide covers a specific area and level, basically you go to an area, pick up a set of quests and then do the quests in the fastest order.
I thought I knew all the Alliance quests from 1-85, but I estimate I only covered 80% of the quests available and I did them in the wrong order.
I've used the guide to level a Warlock and it took just 5 days 6hrs played time which is half the time I usually take!!
I thoroughly recommend the Alliance leveling guide to anyone looking to level an Alliance character fast.
I also bought a copy of Joana's 1-85 World of Warcraft Horde leveling Guide ebook for $37 and it's almost as good as the Alliance guide (not quite as detailed, but still well worth buying).
Both WOW leveling guides use a very similar format and like the Alliance guide the Horde guide also opens up a lot of quests I'd overlooked previously. I leveled a Paladin in 4 days 23hrs. not sure what it is but leveling Horde 1-85 is faster than leveling Alliance 1-85 (is it just me??).World of Warcraft: Cataclysm
is awesome BTW
