No reason to complain or gloat, agree 100%. On paper we should cruise to the semis so if we don't get there, huge failure obviously and if we do get there, that's when it will start to get interesting. Overall though I'd say Dubas deserves some credit for the team being ranked as high as it is (though to be fair, he was put in a dream position to begin with) and the coaching has been good as well. You could pick at some minor things but the same could be said for any coach I guess.
If that's what you think then you're listening to the wrong people. I suggest you look at what the bookmakers say, they're not always right but they're almost always pretty darn close. They had the Leafs as the best team in the North by far when the season started, that never changed during the season and after the season ended the Leafs were still huge favourites to win the north which directly contradicts your hilariously wrong contention that other teams were better built for the playoffs.
The bookmakers were right, just like they usually are. Pay less attention to twitter, your spreadsheets or wherever else you're getting your ideas from and pay more attention to what the bookmakers say. You're welcome.
