Yea, and unless you are a Scrub, there is no Problem.
Having the Mythic RaidGuilds getting a Weekly Item without running Mythic+ Doesnt change a thing there.
You realize that this has nothing to do with the Weekly Chest?
The "Nerfs" are only relevant to End of Dungeon Loot. And are in place because you can generate gear like tenfold in Mythic+ in relation to Raiding.
You get what? like 3 Items/Boss. Thats 30 Items/Week Split on 20 Players. Thats around 1 Item/Player/week. For around a few hours if you have it on Farm.
Now, how many Items can you farm in Mythic+ per week?
Anyhow, either you are Trolling, or you are just complaining for the sake of complaining. So I´m done with you.

I think he meant repeats in the same Chest. So you have 3 Different Items. I would think its safe to assume that way.
Obviously as unlikely as it may be, You can get 3 Weeks in a row the same 9 Shit items.
