The relic will be obsolete from at least 3.2 to 3.25, as Yoshi mentioned the next stage is in 3.25 (assuming it is not delayed).
My 2 Cents from the Letter on 3.1 and How to Address it Moving Forward - copy pasted this post from Reddit where I posted it a few mins ago
Gotta say, I appreciate the Savage and Diadem stuff, but Anima part is pretty disappointing. I don't really feel he understood the main complaint of the Anima quest.
Yes, some people were asking for more challenging content to be an option, but that is just it, they wanted it as another option - not a gate.
More importantly, people wanted the grind to be more interesting and add something new to the game. We get that it's supposed to be long.
I think probably most importantly is the concern of relevancy. He has flat out now said that the relic will be ousted by the new tomestones weapon in 3.2, and that the relic won't catch up until 3.25? He then added that the savage weapon will likely be even higher than the tomestones weapon. I am already 35% done to 210 now, so I'll just finish it, but this is very disappointing.
Hey there
I think you hit the nail on the head here. The easiest way to prevent burn out on the grind is having lots of options. Not only does that appeal to more players who prefer different content, it allows players to rotate what they are doing and do different things. They sort-of did this, and so far I am not burnt out as I have been swapping between roulettes, hunts and alex. That said, I think more options is always better, and I would like to have seen the ability to use GC's, Wolf Marks (even though I hate PvP) etc.
I also am fairly disappointed about his note on the crafting aspect. I would much rather a situation where crafting pieces is way you can cut down on the time you need or something, and be able to choose to get say 4-8 more of each Unidentifiable piece which can be used to trade in for the crafting materials at a vendor or something.
