Why should everyone have talis and opanials? I'm really not sure why you think everyone HAS to get new gear. Why add more OP stuff? When everyone can have some decent equal stuff and then customize it with the spirit stones they pick + their play style to either win pvp or lose.
Edit: I dunno who from Forever you think you talked to but there's a big difference between some members of Forever and the core of the guild who made the guild what it was. Most everyone has had a lot of real life changes over the years. The amount of time and money it takes to win isn't sustainable for the majority of people. You don't even want to know the amounts some of us spent. Getting up at 2 or 3 AM or whatever to do bosses gets old. A number of people are now married or otherwise have very different lives. It was not "boredom" that made people quit.
