They are nerfing a lot of the more punishing one-shot mechanics or mechanics that require a certain class comp. Corobus submerging for one second longer makes running out way easier -- I don't deny that it's going to be a huge quality of life change, but it is a nerf to that encounter. (It is a huge quality of life change because of things like: high latency players, players with lower end graphics cards not being able to see the graphic, etc.)

Similar is true of the wind direction on the VP boss or the tornados: If you were perfect, and never got hit by a tornado, then you could beat the encounter. Now, even if you get hit by a tornado, you'll probably be able to recover.

I think that changes like this are important: They are basically lowering the number of "You were in the wrong place at the wrong time: You die." and replacing them with "You did the wrong thing by moving/not moving/whatever"; even players who have a high level of skill who hit a bad lag pocket can suffer to some of these encounters. I think these changes are all for the good, but they are definitely making it so that it is possible to be a little bit slower, take a little bit longer, make a few more mistakes, and still survive.

And I think that's a good thing. I don't htink there's any reason why Blizzard would disagree with that statement. It's just part of what is actually happening here, and it's silly to say "They're not nerfing things" in response.
