How long does it take to reach max level?

Any insight into reaching max cap?

This depends on a lot of factors:
1.) Do you have recruit a friend? (Speeds it up a lot.)
2.) Do you have an 80 already? (Full heirloom gear speeds it up a lot.)
3.) Have you leveled to 80 before? (Knowing where to go is VERY helpful.)

I'm sure there are a bunch of other factors, but those are pretty key.
