guys stop with the boosting, you all know Sam does NOT have a high level toon he can rely on to boost his herd (and won't level one solo. it's 26 or not basically)

Sam, in my previous note i commented on boosting, because it was your example, but obviously this is for 5 man groups (or even 4 man+booster)
I also said it would not work for your group of 26, and that "your best bet was quests".

If you're going to be killing stuff anyway, why not pick up the quests? grab them on five toons, share them on 25.

Heck one thing i would suggest if you don't want to be 'questing': STILL PICK UP ALL THE QUESTS YOU SEE, don't even look at them, and go do your grind thing.
Chances are, you'll be completing the quests without realizing it, as there are quests for almost every mob in the game. And that is a hell lot of bonus xp.

What's the worse that can happen? your quest log will be full, and that's just a couple clicks in Jamba to fix up.

Good hunting.
