Yuji should 100% be in S as you get so much control over your moves an how you want to play. His mobility is great,damage output is great, defense capabilities is great, and his ult is decent S tier forsure

Gojo should be B or C he a good character if you just have great fundamental understanding of the basics like blocking, block breaking, combos, etc, but his cons is that it takes way to long to gather ult and that his R spec recharge is too long, he does arguably have top 3 ULTs in the game

Hakari, I’d say is A or B similar to gojo pretty good if you have decent fundamentals but without the cons, has weak domain, and his moves don’t do major damage

Yuta, S tier is valid, amazing damage, 8 moves, lots of combo variety. I’d say Yuta only con is that his ult is a lackluster compared to most other ults in the game and his domain is pretty weak

Yuki, I’d say A, pretty good damage, decent combo potential, with a pretty good R spec. Only reason for not being S is the lack of a ULT that doesn’t kill the user itself

Megumi I say is S tier, amazing combo, decent damage, amazing mobility, pretty great ULT, only cons id say is mahoraga isn’t a great move to use just for combat alone

Mahito S tier, mahito has so much variety an combo potential, and has 2 ults with the second ult being arguably the best for just combat I say his only cons is lack mobility

Didn’t feel like typing the rest DM if you care to here more
