You're cherry picking by only considering a season where those teams were anomalously bad. In fact, Kings were on a four game tear when everything was shut down. Kings and Sharks are both performing better than they were last year, and it isn't because of lower competition. The Ducks are basement, but can be a giant killer in any given game, similar to Ottawa. All three are still physical and difficult to play.
You also fail to consider that West has added MIN, COL and STL to the "Pacific" mix. Granted, StL is down with injuries right now, but they aren't a team to be counted out.
I'll grant that the lower half of West is what it is, and I'll counter that you can't name four Canadian teams that can win a series against Vegas, Colorado, healthy Blues, and Minnesota. Maybe Leafs, but that's arguable. Yotes are struggling but it isn't defensively, same with the Ducks.
Unfortunate, without interdivisional play, it will come down to playoffs. Leafs will probably make the semis for the first time in forever, and then will probably be summarily dismissed by their semi opponent. Then will come the excuses and the extolling of the Mighty Leafs who made it to the "conference finals". It will be little more an achievement than the Blues making it to the SCF in their first three years.
