What skill is required in normal raids and roulettes even at 90? You just show up and you win even if you play like an absolute candy man. Enrage and perma death has been removed long ago so there is no longer any penalty for failing or being bad anymore unless you manage to wipe. Skill issue doesn't really come into it when there is no reason for a lot of people to even bother trying. This is not something new with level 90, it's been going on for a long time now.

Most people that play this game play it casually and simply do not care about optimal rotations or gameplay, it is also not up to you to call out if these people are bad or lazy at the game or question their gameplay, just keep your head down and focus on your own gameplay. Unless you are doing actual endgame content who cares about skill. Let them get on with it. If you think it's a slog or holding you back you can just leave and let someone else join in your place.

If they brought back enrage or perma deaths again then maybe I could see a point to the complaint, but Yoshi is determined to make the core game as brain dead easy now as possible so he can reach more players. From the financial standpoint it makes absolute sense, why throw free money away? It is what it is, and personally I don't think it's that big of a deal.
