After having mostly used the free daily quests to get to 66, I use my 66 to run mau, or level up pets/make $ on any map or quest.
Then I go to my alt war and grind him through gy to enter higher mau levels, while alternating to gold farming in esg to make $ for my main.
I've found that in al I need to mostly only ever work on one main, whereas in pl I used to be able to cap multiple toons.
