Should i just run dungeons or stick to questing?

dungeons? questing? what kind of n00b R U? dont you know where the real XP is at? okay, just summon your firehound because it will be a long walk otherwise. travel north to the orgrigan woods and get off your firehound. then summon it again and travel back to where you were, get on your shiny scaled dragon (must be lvl 62 to summon without a mana boost) and travel west. but the only way for this to work is for you to do it slowly, in steps. you must only travel 10 steps per day (it will take about $14.95 - i mean 1 month for you to get there). once you reach the third brown gargoyle to the right of the night elf statue, log off your WoW account for about $29.90 - mean 2 months. when you come back, you should be surrounded by level 2 ground-hog fish. each one is worth 450 xp so you should be leveling in no time.

since u can only queue as dos, doing quests will probably be quicker for you

I have a glitch on how to level faster
Go to the beginning dungeon
press alt F cntrl U alt C cntrl K and cntrl alt delete U
After you press those button proceed to disconnect your Ethernet chord and feed it to your mutated parakeets who have been longing for a meal.

The easiest and FASTEST way to level, great question lol...

check out this 1-85 in-game levelling guide you can buy over at wowlevellingguide.net

It's basically an in-game addon, which detects what quests you've done and guides you through a pre-determined quest route to help you level up as fast as possible, saving you from doing those time-wasting quests that reward u with very little. It automatically guide u using an ingame arrow where to go, and automatically updates as you play through the quests... highly recommended mate. As far as i've seen, this is the fastest way to level up, i've tried dungeon grinding, pdf quest guides etc... but this in-game guide really makes a bloody difference. I've used it with 3 characters now, they're all 85 it's great, I don't quest without it now
