World buffs are not a requirement to kill bosses. They are self-imposed requirements by guilds or raid leaders. If you aren’t adult enough to say “No I don’t want to use world buffs or participate in getting them” or join a more casual guild, that’s on you. You are adult enough to get a job and pay for a sub. Otherwise you’re a child and should get a parent to help you download Roblox.
If you say they create a toxic environment by allowing players to be killed with them, don’t participate in ganking players.
If you say players use them to cheese the bosses, then what about flasks? Or stacking certain classes, or using certain specs? The list will never end. Trying to control how others play the game while it doesn’t effect whether or not you will kill a boss, is in the end none of your business.
I get that players created a super toxic environment with world buffs, Meta’s, and other things like kiting Teremus to Stormwind. But at the end of the day, they were removed in SoM and left in Classic. If we saw a fresh Classic, I would hope they would keep them in.
