I like all three factions, personally. The Cabal seem like the exchange in a sense and the Accord seem like the "good guys" of that spectrum... I might go with the accord. Just because I want my guy to be pretty neutral. I guess I could always switch factions but I don't know how that goes with The Cabal and The Exchange. Things might get messy. Lol
My character is relatively neutral. I worked with Outlander to set up a contract where Evie can essentially take jobs from other people so she's not limited to being just the "Good" guy and instead can follow her own definition of morality and what she thinks is good.
