POE 2 Atlas permanence

I was wondering ig the new atlas will be permanent like the delve is now or if it will be reset every league (like the poe one)

because it takes me more than three months do go anywhere on that thing.

You can actually reset it yourself at will.
(revealed at Jonathan interview, to counter bricking the Atlas)

Well Johnathan wasn't sure exactly how you can reset and not 100% on if it'll be there at launch. so take it with a grain of salt. I am sure between leagues it'll reset and if you brick atlas at beginning by failing first 4 maps it'll reset. however we have no idea how you can reset without bricking map yet, that hopefully is implemented but we don't know yet.

I don't play the insane hours of streamers and full time POE players so i am not worried about mine being way to big, but by time some of full time players get massive atlas maps i am sure there will be a solution if not already implemented.
