Perhaps in the long run DA:I may end up being good for Mass Effect. I'm sure by now Bioware has heard the negative feedback about the side quests in DA:I. Maybe that means mistakes that were made with DA:I won't be repeated in ME: Next.
Feedback about DA2 didn't affect ME3 (dialogue wheel improvements were not carried over; sidequesting problems were repeated; filler problems were repeated; plot-flags-on-import problems were repeated). Feedback about ME3 didn't affect DAI (multiplayer is merely inspired by ME3's, not built from its experience; the sense of urgency and pacing problems are identical; and while the ending plays it safe; the official reactions to the ending reactions were as idiotically handled).
I'm pretty sure we can expect ME4 to retread the same old mistakes two or three times over.
You mean being given a great game that others were incapable of appreciating because they lacked the imagination to enjoy an ending without everything being spelled out for them like a child needing their hand held while walking across a street?
Didn't your mother teach you that trolling is rude? Many a life had been lost in the Ending Wars, and it would appear you haven't learned the main takeaway from them: any ending that contradicts the preceding body of work is a crap ending, regardless of how many people "got it", liked it or hated it. It's just bad writing.
