I just don't understand why they need endgame gear without any useful way to use it
So what? I have no idea either but it does not affect me in any way so who cares. Why would I be against it? What they do with it it's their business. Everyone has its own way of having fun, if they like to do Wanderer's Place HM in 130 let them.

The problem is that a majority of ppl think that raiders are elitists, but they're wrong.
When you think people shouldn't get gear to a certain ilvl because they don't raid, you are.
