Thanks for the advice Khatovar
I actually thought about that some prior and decided to just roll 4 new characters up, trying to think of names that tie in with the Aelli theme so I can swap them out whenever but playing 4 new classes will make it a lot easier to see what others have to offer.
I'm going to probably level up SK / Mystic or Defiler, leaning towards Defiler after what you mentioned / Warlock / Troub.

Now to what Lyonheart mentioned, your composition is pretty much what I planned on possibly having at 80 since the Warden is an extremely strong solo healer, I just haven't played any others so I don't know what they can do, how do you like the synergy of that group?

For your question though, I quested through all of Timorous Deep, Butcher Block, and Enchanted Lands and I didn't quest after that point until hitting Kunark and doing Kylong Plains / Kunzar Jungle and the other one.. it's not ringing a bell, I had just started Jarsath Wastes when I dinged 80 with about 110 AA's, the rest or I should say most of the time from 1-70 was doing the dungeon crawls, which is probably the area that I liked the most because it helps you learn how to play the classes you picked the best. Currently about 3 days later after hitting 80 I'm at 125 AA ~ ish on all of them and I have so many places to quest, which I feel is a pretty comfortable spot to be in for AA's with the amount of time it took to hit 80.

So formulating all of that together..! I plan on doing about the same strategy with the next set of classes and then when I hit 80 I can just mix and match whenever I please. Seems simple enough hehe
