Well, for starters this was a given, the weapon that now are the strongest you can get becoming obsolete later, that is.

What would the point of new relics be if they are weaker than the ones we find in the 2.0 series otherwise?
We are having an easer time than those who dont have it. They said that. Maybe slightly, maybe remarkably notisable... no one knows, just like we dont know when the 3.1 will come out, too.

But lets remember the Atma pre buff version, the Animus books pre nerf version, the Alexendrite pre buff version. These guys have shown us they can put quite the astonishingly time consuming tasks for the sake of attaining that one raidless-requiring end-game stats personalized tools of mass murder. Which of course I, like anyone else, cant confirm you wether they will be customizable. But I believe they will since thats a charm for the relics by now.

In the end its up to personal preference if one wants to put up with it to the end, but we know nothing about what they will bring us up against, or when the patch will happen, or how much worth has our zeta for it. I mean, what if this new relic from 3.1 takes a toll of work to make comparable to attaining the Relic from 2.0 from the starter Relic to the Zeta version??
