I leveled 5 shammies together with quests till level 8... then replaced my main shammie, with my 70 fury warrior and headed into RFC. It took absolutly no time to get them to the twenties.

I finally stopped the "uber carebearing" at 22, and replaced my warrior with my matching 46 Shammie, which is meant to be part of the team when finished.

So while I'm still twinking (with a 46 in the group) my leveling has slowed by a huge margin. I just got the kids to 28 last night, so they could start the Nesingwary quests in STV. Because they are all kill quests, they FLEW by. My 46 (Enhancement twinked shammie) would do all the damage, and the 28s would heal him and toss a lightening bolt in once in a while that would be resisted

Anyways, they got an enormous amount of xp for that quest, and I finished the night by ding'n to 29.

Having multiple toons means you can do things you can't on your own. So far I'm finding success in running quests that are 3-5 levels above my group. The xp payout is insane, and it goes quickly because I have 5 toons helping.

But for the first 1-20 levels, as many folks have said, they will kick your face in. Don't give up. If you can, get twinked through some instance and pick up a few levels in a matter of hours.

Boom
