Pretty Much, and to be honest this is partially why I believe this strike isn't going to help at all.
1 - It's clearly obvious the devs wants to section out a particular part of the game for it's high level of difficulty. While having the game at it's core accessible for as many people as possible. That's clearly a mission statement and would not change any more than WoW diverging from it's core dynamics.
2 - This toxic behavior is constantly seen from the "get gud" who demands higher levels of difficulty for their enjoyment while demeaning those who enjoy a more casual experience.
3 - The changes reflected here would apply to all 3 categories (European, American, and Japanese.) Unless this feedback was given from the three different locations, there's no way they're going to adjust the content to fit a small vocal minority in one demographic location.
4 - Forums in general are mostly a place where people go to criticize content. If the feedback was as massive as some give credence too, we would be seeing these changes with dawntrails. Instead, we see the opposite with even more damage migitation given to tanks. This clearly gives the impression that there is more feedback being given that tanks are too squishy and need more self protection.
