How long does it take to hit 85 from 56?

Hi guys, I was wondering. How long would it take to hit 85 with my current level. I am talking with about an average of 8 hours of game time per day. Currently I am using BM spec to level.

Could anyone please advise?

Also, is pure questing following a guide faster or constant dungeons with a little questing as dps has a longer waiting time.
Is your main in the guild u are in? cause you can buy the BOA shoulder/chest/cape/helm which would make lvling really fast.
Nope. This is my main. haha
Leveling tends to slow down at Outland quite dramatically. With the update to Old World, OL is, in my opinion, one of the slowest phases of leveling. Lots of "Go here, collect 20 of this item that drops from one bloke 3% of the time" (Credit to Zero Punctuation for that one).

Northrend tends to be more interesting, and thus passes quickly. Same for 80-85, especially on your first time.

Leveling speeds vary from person to person, and depend on class, spec, whether your leveling proffesions etc. My advice would be to chill out and enjoy the leveling experience - you only experience everything for the first time once, as confusing and sentimental as that sounds.

And level cap can be more boring than leveling, sometimes.
6 months ago 56-70 took me 60 hrs. Outland and BG weekends.

last month, 61-70 15 hrs. hellfire, 1/2 zangarmarsh, nagrand, borean..
had good gear and enchants and could solo all the 5 man quests

last week 70-80 37 hours dragonblight, zuldrak, sholozar

80+ LFD is great, good items and decent xp, runs only take 30 min

instances are slow leveling, and not worth it for gear you'll outgrow in a day but you can get nice blues from LFD and justice points later to buy BOA shoulders for xp bonus. Also, if you can just find a high level guild for xp bonus and other perks, do it.

train herb/mining (tons of xp from it, but not from skinning?) and gold or mats for your final profession, get a speed enchant on your boots, gathering on your gloves, buy the fastest mounts asap, use carbonite.
One thing that really helps, buy outland gear from AH at 67, buy cata greens at 77 2-3 levels before you need them. The gear is so much better than anything you can find in zone - you will fly thru quests.

You can prob average 4hrs per level.
