I'm a very party-oriented guy when it comes to MMOs. It's due to this disposition that I enjoy playing Healer classes, and it's why I would like to play as a Settler. Give everyone some buffs, build some buildings that benefit everyone, etc. My main concern is that I hope the Settler remains relevant even when there aren't many players around (like let's say a few months after release if Wildstar suffers a similar player drop-off as other MMOs). Fortunately Carbine said that even without other players, you still have a 'bunch' of quests that involve interacting with NPCs, so hopefully that means there'll still be good reason to be a settler even with fewer players around.
