Bard Power leveling? How it works

[Cords]

Hi guys, I have only ever soloed or grouped my bard. I know that you could potentially power level someone with a bard, swarm kiting, with a FD class is something I've seen before. The question I have is how do you power level someone who doesn't FD, and are they in your group or out of your group and get exp from an aoe spell?

I don't really like power leveling because it takes away from the game, but if i can help a friend get a few levels or to get out of hell levels then I would like to know how to help them.

Thank you..
