Levelling question (old PLevel trick)

So working on evaluating how to quickly powerlevel a 30ish sorc using my lvl 50 jugg and open to suggestions.

back in eq/eq2 and even WoW (as long as you did it right) if the lowbie 'tagged' the mob you could kill the mob with the high-lvl toon and the lowbie would get a ton of exp (toons not grouped).

this seems to be the case for swtor at the moment also.

has anyone found a quick 'grind' location layout - possibly heroic mobs or something by level? or know another way to level a toon quickly? I don't necessarily need to 'experience' the game again, more looking for a healer-bot to duo with my jugg.

open to suggestions - if there is another quick-level method I'd be open to that also

thx - these forums have helped me a ton with multiboxing over the years, definitely appreciated. with swtor being a new game, not as familiar with some of the levelling techniques yet and so leaning on others experience

I would just go to any world heroic area and grind away.

You cant do that in WoW anymore. You need a certain percentage of damage to get the kill, simply tagging it is not enough.
