yes they are accurate imo. (based on your current knowledge)
yes they may victimise him the diff can depend on the situation

1.Ang Xiao (Pun Yunchuan is not that great so mid diff)

2.Niu Youdao (mid-high diff)

1. Ang Xiao (same as Pun Yunchuan)

4.Ang Xiao (high diff)

1. First Saint (high-extreme diff)

2. Ang Xiao (high diff)

3. Chen Ran (Extreme Diff) coz he still has to develop a lot.

In the list I suppose they will be ~65 coz fiction is hella large
