Nobody's arguing ranged jobs are in a worse place lmao. Stop trying to deflect from the fact that samurai's kit is fine as is. MCH LB being instacast with no counterplay is fucking stupid, everyone knows that.
I'd argue the opposite. Leaving cast time on midare is fine because of the damage it does but something should be done with namikiri, like scaling damage or something to justify it having a cast time. Or have second cast of iaijutsu after midare, no cast time. Like higanbana and having that dot. Idk, there's options to make it more feasible.
