First off, yes I know theres a ton of dailys guides out there, however they focus on the obvious, and list simple, commonly known facts. What this guide does, will teach you not only fast routes, but also which you should skip if you're on a time limit. Note, I do not cover the cooking dailys etc.
Isle of Quel'Danas:
This section of the guide is largely dependent on your server's progression, so obviously if "X" quest isn't unlocked, you can't do it. First, we'll go over what quests you should, and shouldn't do.
A Charitable Donation
1 out of 5, skip this at all costs.
Arm the Wards!
3 out of 5, the droprate can sometimes be a pain
Ata'mal Armaments
2 out of 5, this quest isn't hard, but the location for it isn't favorable.
Crush the Dawnblade
4(3ish) out of 5, this all depends on how fast you can grind. For the most part though, do this daily.
Discovering Your Roots
1 out of 5, unless you need the rep, skip this. This quest is annoying, and is in an odd location. (Note: If you have an epic flyer, I would probably do it)
Disrupt the Greengill Coast -
5 out of 5, Do not skip this quest, it requires 3-4 kills, it's THAT easy.
Distraction at the Dead Scar
4 out of 5, The only bad thing about this, is you may have to do multiple rides, depending on how many other people are there doing it, and how good you are at bombing quests.
Don't Stop Now....
2 out of 5, While this quest seems easy, the droprate for the keys can sometimes get pretty rare. I recommend keeping this in your quest log, and do a little each day.
Erratic Behavior
5 out of 5, Do not skip this quest, 5 kills, and the elementals are very squishy.
Intercept the Reinforcements
5(4) out of 5, unless you absolutely hate bombing quests, don't skip this. It's very simple, the only reason I didn't give it a strait 5, is that you only get 7g for it.
Know Your Ley Lines
4 out of 5, a "conjunction" quest. It's very simple if you're in the area.
Open for Business
5 out of 5, Do not skip this quest, this is another "conjunction" quest, it's very simple. It takes 3-5 minutes, tops.
The Battle Must Go On
5 out of 5, Do not skip this quest, this requires 6-7 kills. (Note, you do NOT have to kill the emissary of hate, you can use the item on ANY dead corpse of his)
Skyguard-Terrokkar:
Fires Over Skettis
4 out of 5, the birds can be annoying, but for the most part an easy quest.
Escape from Skettis
3 out of 5, this quest is dependent on if/and how long it takes you to find the guy, I wouldn't spend more than 5-10 minutes searching for him.
Skyguard-BEM:
Wrangle More Aether Rays!
5 out of 5, Do not skip this quest, this requires 5 kills. Well, I shouldn't say "kill" since you only have to knock them down to 40%. They're fairly squishy too boot.
Bomb Them Again!
4 out of 5, this quest can be a pain if you don't have an epic flyer, but as long as you're somewhat good at dodging the cannons, you'll be alright.
Ogrli'la:
Banish More Demons
3(4) out of 5, this quest depends on how well/fast you can burn through 15 mobs, not too hard, unless you're on a strict time limit I wouldn't skip this quest.
The Relic's Emanation
3(4) out of 5, sometimes you have to clear an area, but for the most part it's strait forward. On a side note, I wouldn't even attempt this quest unless you have the addOn "Ogri'lazy" which you can find here: Ogri'Lazy
Shattrath/Sunwell related:
Blast the Gateway
4 out of 5, requires 8 kills, and you don't have to personally kill them, either. Just as long as you (and your spark) are near one when they die. (Note, if you die you lose your spark. I.E. you start over again)
Blood for Blood
5(4) out of 5, requires 8 kills (4 to get the vials). The reason it didn't get a perfect 5, is all the elites running around can make it sometimes difficult to do this.
Intercepting the Mana Cells
4 out of 5, usually have to kill 5-6 wryms, which isn't bad since they have a high droprate for Mote of Mana
Sunfury Attack Plans
3 out 5, this quest is a wildcard. I've gotten the plans within the first 5 kills one time, and the next day it took me 42 kills before I abandoned it. (Note, it's possible that it was just personally bugged for me).
The Multiphase Survey
4(5) out of 5, very strait forward simple quest, the only thing that slightly drags this quest down, is the location. I would never skip this, however.
The bottom line (5 star quests):
Disrupt the Greengill Coast
Erratic Behavior
Intercept the Reinforcements
Open for Business
The Battle Must Go On
Wrangle More Aether Rays!
Blood for Blood
The Multiphase Survey
