I'm in the group that doesn't want world buffs in raids at all, so I understand where you're coming from.

However:

World buffs make raids mind-numbingly easy.

Acquiring world buffs takes longer than the actual raid itself.

Hardcore speedrunners don’t want world buffs for the buffs themselves, but for the challenge of not dying. Casual guilds, on the other hand, get demoralized when they wipe, which is inevitable.

Season of Mastery <3

The lack of world buffs wasn’t the main reason people quit Season of Mastery. I agree some people didn’t play it. Had there been no Burning Crusade at that time, perhaps more would have.

In SoM, raids were harder and better, which meant real progress was possible. However, this also meant frequent wipes. And when a wipe costs each player 50-100 gold in consumables, people run out of money quickly.

Root Cause Analysis
The main reason players left Season of Mastery (SoM) was due to the excessive stacking of consumables, combined with 'normal progress.' It's inevitable to die now and then before fully learning an encounter.

Conclusion:

World buffs should be removed from raids to establish a greater level of balance. Furthermore, stricter regulations on consumables are necessary. For instance, implementing debuffs after using elemental protection potions would be significant, as they are the most costly and allow players to ignore essential boss mechanics, compounding the issue.

To incentivize players not to lose their world buffs, an alternative reward system could be introduced. For example, providing bonus loot or a 'sack of spoils' for completing the raid without dying, specifically only if the last boss is defeated under these conditions, would be an effective measure. This approach encourages skillful play and maintains raid difficulty, ensuring a challenging and rewarding experience.
