I like this list
It basically says that 20/27 characters are within two ranges(S- and A), and very few characters are outliners, both as top and bottom tier, and even then, they are not broken or extremelly weak.
I feel Shin falls more in the A/A- category. Too soon to speak about Eagle, but he is a pretty extreme char: Either he has A LOT of initiative, or he has to be super patient to get momentum back.
Out of the characters that could move one placement into this tier list, I feel that(personal opinion in all this):
-Aria, Mira, Omen and Rash are top 4, in that order IMO
-Eyedol is the strongest among the S- tier
-Orchid is the weakest among the S- Tier
-Sadira is the strongest among A- tier
-I have doubts between Spinal and TJ as the strongest character for A tier
-I have doubts between Arbiter and Gargos as the weakest character of A- tier
-Kan-Ra is probably the weakest character(someone has to be)
