The bottom line for me is time when doing dailies. I have 3 chars with which I do dailies and I try to keep the duration to under 90 min for all - so about 30 min per char
There are 2 main paths - both have pluses and minuses and the outcome is about the same:
1. The island quests. gather all quests - then start from :
Arm the Wards! > Erratic Behavior > Crush the Dawnblade >
Know Your Ley Lines (1st portal) > Intercept the Reinforcements > Distraction at the Dead Scar > The Battle Must Go On > Know Your Ley Lines (2nd portal)> Know Your Ley Lines (3rd portal)> Don't Stop Now....> Disrupt the Greengill Coast
TOTAL TIME PLAYED -30-40 min for around 100g
2. The outland path -
The Multiphase Survey > Bomb Them Again! > The Relic's Emanation > Wrangle More Aether Rays! > Intercepting the Mana Cells > Sunfury Attack Plans > Blood for Blood > Blast the Gateway > port to shattrarh
TOTAL TIME PLAYED - 35-40 min (you can get really unlucky here sometimes) for around 90g and some guarrantied greens to DE and possibly a badge.
Alternatively after the hellfire q's you can swing through SMV and do The Deadliest Trap Ever Laid - which is easy to solo for some classes and its 18g and finish it all with the skettis 2 quests
Second path involves more traveling but you wont have as much competition around and/or gankers (if PVP server). First path is best when done early in the morning since PVP servers are full of nasty rogues lurking in the shadows "when the kids come home from school"
