No. I don't know who you heard it from, but the director never said he didn't like the concept of Aces, don't cut to false conclusions when you didn't even directly read the article.
The director only said that the Aces will be irrelevant in the new chapter, as well as the skillsets. He said that they may or may not appear in later generations.
Oh no?
They're not planning on releasing aces, this new director does not like the concept of ace talents nor the ace characters.
Either way, Chef disappears at the beginning of Episode 1, never to be seen again throughout Saga 2. Starlet and J go poof at the beginning of Episode 2, also to never be seen again throughout Saga 2 (the nightmare Merlin has in Episode 5 does not count).
