Question about quest with other human players.

I've been wondering if I do a quest with another human player, once the quest has been finished, will I get credit for finishing the quest if I already haven't do so?

For example, if I help a player do Minister Cho's mission, but have't completed it myself, will I get rewarded with the same loot and xp and story progression as I would if I was doing it myself henching? Or would I have to repeat the mission again to progress in my quest?

If you are in a party that completes it, you get credit for it. It doesn't matter if it was a party of henchies or a party of humans.

you must have that quest activated (or just in your quest log lists) and when you passses it with friend its solved. but if you passed it (helping friend) and you dont have it yet in your quest log you will need to pass it one more time. you will get all exp like him and so
