Oh snap! I've already answered in another threads a few minutes ago. KK Quoting myself again
Flaws and ideals aren't as important to me as to join factions for side quests, to benefit from faction-typical privileges and ofc to dive deeper into immersion. There are special backgrounds that are predestined for this but unfortunately are not yet in the game, which I would like to have added. See below:
Edit: - more (immersive) backgrounds such as Guild Merchant, Mercenary Veteran and Faction Agent
Especially the last two make me curious. Choosing that backgrounds and joining a faction / being a sell-sword for all the mercenary companies would be awesome. There is a lot of potential such as encounters with the infamous Bregan D'aerthe and completing assignments for them and other mercenary companies. The Zhentarim and Flaming Fist are already part of the Game.
