I just hit 50 a few days ago and finished the story quests. I'm working on my Relic weapon quest and beat Chimera last night. I'm up to the AK part which I know I can do since I ran it before to finish story mode.

Basically what I want to know is can I fight the primals in my AF gear plus filling in the other slots with DL gear or do I need to be full DL? I don't want to gimp the group I do it with but I also want to get the weapon as quickly as possible. After that I plan to farm AK. Thoughts?
