9S Automaton is not appearing per patch notes

[Zofis]

9S was not a 100% drop at first.
Now, it's still not guanranteed, but instead of fightning your roll with 23 others people, it'll only be with your own alliance.
That's what it actually means.

I'm aware, but the issue at hand is the patch note wording—both in English and Japanese. The patch notes clearly indicate that the intent was for there to be parity between Tower and the previous two raids in terms of drops now because it's identical in wording to when the other items were made 100% drops in 5.5 proper.
