Its different.

For Assassin, MHX already have good stats to begin with;

The problem would be her skills, as all of it nearly see no use before skill updates. Then, she got invul. following her update. That's enough to make difference as newer Rider enemies have easier access to higher damage (Ivan, Orochon Tree) while making her decent pick for older enemies (like Ozy or Quetz, basically where she previously not so good to consider).

So she's already good since she got invul. by meant of dealing with Rider enemies; Skadi is luxury if you want her third skill see use by overcome Assassin multiplier or just NP spam to looks like a boss, which closer to personal preferences rather than 'weaknesses fix'.

Meanwhile for Saber, there is consideration about there's no "major" Lancer boss for two years. So the valuation took "who can deal with non-Lancer situation better" as well; its not like she's bad, but other Saber can handle situation that did not have to be against Lancer better.

Musashi have more difficult deck but she can bruteforce it without waiting NP while having good resist and invul. to cover her. Arthur can not NP spam, but amount of large enemies does put him on better spot given his third skill allow him to contribute for demon pillars at Part I also Lostbelt I & 2, which is nice for people who want to work hard rushing stories.

I personally found it hard to put Okita on same place with them as latest Guda Guda event seems to acknowledged that Nobu and Okita need update with them going damage bonus.

Then Skadi happened, not that its bad but IMO it helping DW to take it easy with older Quick if difficulties they planned still allow consistent OTK (or at least high damage crits) with just one Skadi support for them or solvable by other way (being cockroach like Cu) thus 'excuse for no skill update'.

Who knows if Caenius or that Shoukaku-looks-alike Lancer will make a change that enough so Okita can get skill update. Just don't expect it to be a big update as DW is smarter than two years ago; they'll make it enough.
