Level 63

Hi. I just hit level 63. I have not joined a faction yet. I am using Bow / Rapier and a Dex / Con build. Medium armor set. I have no idea if it is good or if I am moving in the right direction. I play exclusively on my handheld Retroid Pocket 4 Pro via Xbox remote play. I don't like to speak on mic.

What expedition/ raids should I be grinding?

I enjoy pvp, should I join the largest or smallest faction?

Thanks in advance. I am open to all advice.
