Well heres a trick for you all, it really takes the pain off of 1-45 grind / questfest and speeds things 10x faster than what you would usually level at.

You should be always sitting at about 30k-60k exp p/h at all times.

Requirements
level 70 Warrior / prot Pally / ice Mage (Any one of them)

I personally use pally and soon to use mage for this, my methods are as follows.

Run 5box through instances with your ice mage / prot pally / warrior aoe's
You should be able to do stockades and almost every side of scarlet monastery in about 3-4 pulls.
If you are running mages through software boxing make sure u can alt tab to one of them to keep blizzard on the targets so they dont run from your main to make things faster, if your hardware boxing you know the drill.

I also have tried some risky moves in the last few days with the first major pull of SM cath, where my pally would have all mobs down to about 5-10% then zone out the instance and let my alts aoe's finish the 30+ mobs that are hanging out there, all die non rested for full exp 360 per, and when you work it out the first pull if you get it flawless with the zoning and pulling = 10k exp flat.

1-10 Solo grind 4box
10-15 Deadmines (whatever you are comfortable with)
15-25 Stockades 3 pulls
25-45 Scarlet monastery
(Library for 25-35) 4-5pulls
(Armory for 35-37) 4 pulls
(Cath for 37-45) 4 pulls

If you are having someone else controll one of you 5box accounts then you can also earn about 350g p/h in SM as a disenchanter
