Based off the JP tier list here http://exvsrank.ninja-x.jp/list.html
Thought it might be interesting to discuss changes over time / see if overseas players have different thoughts.
The list was just updated (1.29) and I don't know if the site has a list of the changes made, but some I can see:
3000
I forget the exact positions after WZTV and Reborns, but regardless Unicorn is now up a few places in the same tier as Reborns, but still both after WZTV. Turn A might have moved up a bit as well but I forget.
2500
S and A tiers seem to be the same, except Deathscythe is now ahead of Xenon F. Also either Extreme Eclipse went down a bit or Extreme Aios went up because they weren't that close before. Anyone notice anything else?
2000
Delta and Hambrabi have been shoved into S tier joining Zeong and Kshatriya. Gyan might have moved up a spot or two, don't remember.
1000
1K seems pretty different at the top at least. EZ8 still first, but his A tier status is joined by Zaku Kai and Hildolfr
