Duo Question (Magicican & Enchanter)

[Tkon]

Been doing a lot of duo'n w/ my enchanter friend as of late and we're level 50 now. Was wondering if the 1 point of damage rule still applies to a duo to get the full experience versus 25%. I ask this, because a lot of times we end up just letting my pet do ALL the work, as in 100% of the damage and it just dawned on me this might be eating up 75% of our exp ><

Thanks
