Agreed
If they use their powers wisely it will be the OP ever!?
I agree, from this we can see every power is equal.
Class F are classified as not useful since they are restricted on the things they can do on their powers but if you really think about it, their powers doesn't really have a "limitation" like when the mc can view the birthday of a person through pictures or video. The 1min time travel also doesn't have a limitation on how many times she can use the reverse 1min which basically means she can continuously reverse time as long as its in a min.
Honestly, their powers is kinda OP you just have to find the loophole in order to maximize their potential.
