If I want to do NW+15 but none of my mates have that key, I have to go and seek randoms who have it. This is not about the weekly affixes - those are actually fine. This is about just the number of keys and the randomness.
You pull one extra mob and there’s a good chance your key is degraded. Obviously, if someone leaves a party, it’s the party leader’s fault. Imagine you want your M+15 trinket from De Other Side. You fail your key, the hunter left the party and now… you have an M+14 De Other Side key. You no longer have access to the dungeon you need to farm.
Keys themselves are too punshing.
Except it’s not really the player’s choice, as their choices are dictated by the game design. If let’s say your RIO is low and you want to do dungeons, you’ll feel compelled to spam runs to get that RIO high. Players being untrustworthy is why Blizz has the stupid stamina system for soulbinds. Because they learned in BFA that players are too petulant and childish that they cannot be trusted to make good decisions at all.
Also, players spam the same dungeon over and over (problem compounded through RNG dungeon access) hoping to get their bis item of a certain item level. They burn themselves out and then end up here in these forums, hating on the game. This CANNOT be a problem if M+ isn’t a thing.
Game designers know players cannot be trusted to have fun in a game. The game has to be designed in such a way that it is fun despite what the players want to do. Because players, left to their own devices, will not have fun. They will pursue the optimal path to obtaining the reward they want. No matter if it’s fun or not. This is why PVP was so popular - not because it’s fun, but because of the rewards.
Half the threads on these forums are people complaining about M+ and the systems that have to exist as a result of it, like loot scarcity or the weekly vault.
If you could only do 8 dungeons a week, getting 2-3 items per dungeon is fine. You’re limited, so go ahead, take these ~20 items over a week.
Due to dungeons being infinitely spammable, the ~20 items per week soft limit needs to remain, but because you can do 50 dungeons in one week easily, these 20 items are spread over 50-ish dungeons.
M+ is garbage.
EDIT: Pugging raids is not even comparable. Because unlike M+, if you want to do a specific raid, you have direct access to it, and you don’t have to pug. You can be in a guild, you can play with friends. But if none of your friends have the key you want to do, then you HAVE TO PUG.
