I'm not seeing the issue here. They're not saying they're going to nerf ALL the content so casuals/new players wear the same gear as endgame raiders. They're going to be nerfing PAST content, stuff completed by endgame raiders a few months before. What that will do is let new players not spend the same long amount of time doing past content but get through that faster so they can get to the current content. If they don't nerf the content, it'll be incredibly time-consuming to progress through all past content to get to the current content. And remember, while they will nerf PAST content, there will be CURRENT content that is still tough that you endgame raiders can be working on.
