I’ve updated the tier list for Ultra Street Fighter II based off of online data at https://askvance.wordpress.com/2017/09/04/what-is-the-latest-tier-list-for-ultra-street-fighter-ii-september-4-2017/ which now looks like this:
A: Balrog, Chun Li, Ryu, Violent Ken
B: Zangief, Dee Jay, Guile
C: Akuma, Vega, Dhalsim, E. Honda, Ken
C-: M. Bison, Sagat, Fei Long
D : Evil Ryu, Cammy
F: Blanka, T. Hawk
This means Balrog and Chun Li are the first two characters to have more than 20,000 BPs online. They wouldn’t have been my first two guesses, but there you go.
