All you players who say " if you play legend, you should be guaranteed as drop" are killing this game. There should be drop protection period. It should not be dependent on "legendary" this or that. If you complete activities you should get rewards, period. If those rewards are special or limited by number of attempts per week or time or whatever, eventually every one should earn the reward, provided they can do the activity.

Another detail. At the moment I still have energy and desire for the activity, but in about 2 weeks or so, I probably won't have any more, will Bungie force me and suck all my energy just to get what I want?... It ends up leading the player to exhaustion from the game, it seems like a shot in the foot

So Crucible and Vanguard Ops, probably Gambit too (I don't touch that) drop weapons with multiple perks as you prestige. You can even get double triple perks. The doubles or triples are random, singles still drop, but they drop decently enough. We should be able to craft multiperk weapons too. This should just be the model for everything. Combining perks, one would think just ruins the grind, and makes it too easy, but nope; I've done this far too much, just trying to get the right Randy's since it was re-released, and still have not gotten it. Its definitely still a grind. It definitely feels so much more worth the chase when weapons drop with double perks too. I can just have one or two weapons, instead of a whole lineup, for specific activities. They should outright remove single perks from the game and default to double. This I feel, would help the Onslaught grind, because then, even if you're not getting shiny versions, you're still getting double perk rolls. The only special, more exclusive things really, should only be cosmetic anyway. Anything else is just being an elitist pr*ck. We all paid for the game. Very few, Im sure stick with the free version, given how insanely limited it is. This also saves on vault space, so Bungie has less to deal with there, and players can have more equipment slots open if they engage with multiple activities. They have to dig through the vault less to bring the right stuff, and we can still get Adepts and everything we already have. Bungie is always concerned about space, and this is an easy space saver. Quality over quantity is the best answer. Just my thoughts.

I have no complaints been lucky But mercy drops wouldn’t be a bad thing

So in other words, remove the grind and get what you want for basically free? No thanks. The reason why this sounds like remove the grind to me, is very simple. Destiny at it's core is a LOOTER shooter. Take games like Diablo 4, Warframe, and whatever other looter shooters exist in current day, those games are still thriving because of this design. People are still logging in day in and day out to get what they desire. If Destiny followed the "Remove the extensive grind" the game would be incredibly boring, both sandboxes would be rampant with broken weapons (yes I'm looking at you Forebearance. Even though I have an absurdly large amount of kills with it).
