The AA slider definitely adds a little flexibility to the process. I love questing and grinding so having the flexibility to /lock, disable xp, fiddle with the slider really appeals to my fickle nature. It changes the feel of the game (questing vs. grinding), so it's actually a great deal in my book.

Right now, I've got my my first team of 4 at 22 (2 mentored toons, however) and have started a 2nd team of 3 to level up different classes to see what I like best. I can see myself leveling a 3rd group to the low-mid 20s (alts are way too much fun). So far, I've got the accounts organized by class type, ie. all tanks one one accounts, all healers/2nd healers on another, etc. It makes it much easier for me to swap classes in and out.

Team 1 looks like it'll be: SK/Defiler/Swash/Dirge/Inq (5th account pending)

While doing this, my 80 necro is grinding shards during my lunch hour for the SK. Go heirlooms! I may level my 48 fury up a bit to do shard runs with the necro (sitting at entrance..not sure if it'll work but I'll give it a shot) and save up shards for the DPS/Utility account (currently swashie and warlock). If all goes to plan, I should have a fair amount of shards to spend for the SK by the time Team 1 gets to 80.

My goal is to have at least 1 team in the 70s by the time the new expansion comes out. It may be optimistic seeing as I get about 2 hours maximum every morning for playing. I'd also love to get at least 1 epic weapon (Fabled) for the team although I realize that it may be hard without a full group of 6. Modest goals for sure!

Either way, I'm having loads of fun with all the combinations.
