I really don’t agree with this at all. The first time I ran CoE I died a lot too, because I was new at it and had no idea how the mechanics worked yet. I’ve run it enough now for almost the full set (missing 2 pieces) and I now I can do it without dying once usually, he’s really easy actually once you get your dodges timed right. He’s definitely one of my favorite dungeon bosses.
You should probably stop jumping to conclusions and deciding something is broken the first time you try something and fail, and instead figure out a strategy to handle it. It’s not designed to be a cakewalk the first time you go in.
And I like the weapons/armor, sorry you don’t.
