Leveling 80-85 methods

[Ualaa]

I'd think, if you have the option of a legitimate dungeon finder team.
Five toons, one who can tank and one who can spec to be a healer, even if you don't run them that way... as long as you have enough heals and a tank...
You take those five and use Dungeons to level to 90th.
Even if you do trash and then reset and use dungeon finder to avoid the limits on instances per hour.

Once you have a 90th booster...
You can park the alts somewhere and boost... such as Deepholm.

You could also borrow your tank and/or healer...
And level additional toons through instances.

Plus you could park your level 90 team nearby.
And quest or boost other toons.
If you're camped, log on the level 90 team and see how they like that.

Boosting has greatly improved this expansion. Both dungeon boosting and mob-grind boosting are easier.

A couple that come to mind.
AOE looting is simply amazing. Make tons of gold selling cloth drops or save tons of gold leveling tailors.

They fixed the lower level aggro thing. At level 85 sometimes I would have to sit on a group of mobs for a second or two before they aggroed, but now at 90 I dont even have to get that close and can aggro them on a run. It feels so much smoother and quicker.
