This. If the story itself dropped hints as to what's to come slowly the Mafia plot would've felt better structured to me, if we kept the same pace prior to this arc and saw the mafia plot develop more and more after each update I wouldn't have minded. My problem is a sheltered farm kid was giving too much to deal with, too soon. The decision to just jump right in a violent storyline such as this one, so soon should've been considered more. The MC apparently has a savior complex, I was more concerned with the safety of him than anything. If I knew and cared about people for a certain amount of time, then yes, risking my life for them would seem like a no brainer for me. But to know them for only days? Weeks?
That said, I don't think the writing is bad at all, bad writing gets thrown around a lot but there's a difference to me. If the Mafia arc was total shit and didn't make sense, sure. But from what I've played it's been well executed. Players are just exhausted from it and want it to end if anything.
