Circulators and the Unlimited update

So theoretically if one had a lot of NX, you could try getting 3 S lines and wait for the patch and get 3 Legendary lines to cube?

I'm actually not sure how the new system works, but each line doesn't have its own rank anymore. The Legendary rank will apply to all 3 of your lines I believe.

So, it's like this?
0 S -> Regular Circulator all you like, until you get even one S, at which point...
1 S -> NX ONLY!!!

And can I assume this NX Circulator won't derank my S's? And it works like Circulators do and resets all three lines?

Edit: Oh, my second question is similar to Sephie's.

Each line doesn't have its own rank anymore, but I guess it would work like that. You probably can't go down from Legendary once you reach it. Yeah they still reset all three lines.

How much NX are the new circulators anyway?

They're about 1.5k or somewhere around there iirc.

Does the stat remain the same? Ie. 20% Crit before unlimited, 20% Crit afterwards?

Yeah I had 40% avoid to HP before the patch and it stayed the same after.

By the way if you wait until after the patch to unlock the lines you didn't have before, no matter your rank you'll start with 1 all stats (if its the first line you're unlocking), 3 all stats for the second line, and 5 all stats for the third line.
