I hate this as well. If the ending is "safe" as in boring and predictable, then we've only got ourselves to blame.
If the only choice is between a safe ending and a nonsensical piece of railroading garbage, I'll take the safe one, thank you very much.
I don't mind tragic endings at all. Read Dead Redemption has one of my favorite endings, and it's depressing stuff. But ME3's ending didn't suck because it was tragic. To me it sucked because it came out of left field, boiled down the core conflict of the series to a ridiculous programming error, and your ''choices'' basically amounted to ''pick your poison''. It was just a bad ending irrespective of the fact that it was tragic or not.
I doubt Inquisition will go this way. Bioware won't want a second backlash like that. But I still do hope victory doesn't come easy, if it comes at all, and that we have more actual choices in our ending than in ME3 or DA2. Origins is a good model for that.
