As someone who's done almost everything in the game since Season of Arrivals (when I started playing). I would argue that Trials is much harder unless you're really good or have a streamer/friend carry you. You can only get 3 adept weapons/mods a week doing Trials of Osiris, 1 per character every week. Unless you are doing a Confidence Passage which gives you a chance at multiple Adept Weapons, which in my opinion is the hardest thing to do in the game. (A flawless ticket with no loss whatsoever just extra loot at the end). While Grandmasters should give loot even with my luck I have gotten plenty of adept weapons and mods, and there will be easier Grandmasters to farm whatever Adept weapon you want. I feel as if there is no need for a guaranteed drop everytime or else you should just be given a guaranteed reward for every activity that you play, which shouldn't be the case. Feel free to argue with me all you want but I think the current state of loot is really fair, the only argument you can really make is about the master and legendary lost sectors.
