The nerf is good. It was not end game content, just story content meant for all players (including casuals) to do. I'm sure you will get a few dumb comments like "This game is catering to casuals" or "Game is EZ mode nowzzz!" but honestly those comments are just dumb. There is plenty of hard mode content out there for people, and it really is not unreasonable to make content that is meant for everyone (including casuals) be able to be cleared by casuals.
