Let’s analytically look at this from the most greedy perspective possible: how would griefing someone out of loot affect the person doing it.
Yes, they get an item. At the same time, players might leave the raid/guild. If a lot of players leave, and progression stalls, it will become harder to recruit more raiders. If enough players leave, there won’t be a raid anymore. If there’s no raid, no bosses are dying, no loot is being earned. So this outcome is long term bad for the person doing the griefing.
At the same time, I don’t think it should be blizzard’s job to stop players from shooting themselves in the foot.
You can believe whatever you want. Ill put more stock in what actually happened a few years ago in legion though where it worked out just fine.
Like I said we dont need to play hypotheticals because it actually happened.
Players who are not a part of the world where people work collaboratively will find it hard to imagine it working but that’s fine. They don’t need to use it. I play sports at a pretty decent level but I find it hard to really think about what pros go though in a weeks prep for a game. Doesnt mean they dont do it effectively just that im not a part of their world.
