Hehehehe.

BC xp is twice the xp versus PreBC areas. So 58 is the best time to send nubs over.

If my alt is 58 and hits a red mob for 1hp damage (thereby tagging it), and the other toons that are dpsing can con the exact same mob as green, then alt 58 is going to get full xp after group of 70 kills tagged mob.

Tag with nub, kill with 70's and boom full xp. That means I can run around pull 8 mobs tag/dmg the mob, then 70's can aoe and fat xp. If you guys didn't already know. This is how someone got to level 70 within 24?48 hours of BC release.
