I think they’re fine as is. I try not to be part of the “Grrr streamer/youtuber bad” group, but I will say that people who make a living by playing games all day shouldn’t be listened to when they talk about things being too easy. It’s how you get a dungeon like duality, which I may think is fine, but obviously a lot of people didn’t like the difficulty compared to other dungeons. Although thinking about it, the main issue I see with making GMs harder is that the enemies will just become stronger. Which is an annoying artificial difficult that in my opinion doesn’t fit destiny in the slightest. The game is at its worst when you’re sitting behind cover, and is at its best when you’re able to use the full range of movement, weapons, and abilities that the game has to offer. Bungie would have to increase difficulty by adding and changing the extremely basic strike mechanics, which I’d be fine with. However that’s probably never going to happen.
