Yes, it is really disappointing. Season 1 was so good with daring storyline and animation. I think they toned it down for season 2 which is fine if they can maintain the quality storytelling. Sadly they can't. Most of the episodes are pointless in the ending. The last episode said it best. Nobody will remember it after a while.

Totally. They rushed it. And that was a mistake. The series was good enough that people would have waited for a completely new set of stories no matter how long it would have taken. They did it for Mass Effect (video game) because that, like this series, was excellent. And instead of following the story that worked, the production company tried a "new approach" and it didn't work out like they had hoped. The production company rushed the next iteration, and it turned out more people wanted to forget "the new approach" than those who somewhat liked it. People will wait for quality; not patiently, mind you. But they will wait.

IMO, third season is definitely an improvement over the second one
