Looking at the marginalization aspect.
S1 was about Pike wrestling with his fate. His story was the overarching arc of the season and was the focus of the premiere and finale. Even so, his approach with the Romulans started a war while Kirk's more aggressive action stopped one (Vulcan Hello 2.0).
But outside of that, Pike was rarely the focus of the show. E2 was the Comet episode which was Uhura centric. E3 has Pike/Spock on the B plot again with Una the focus. E4 was straight space battle with Pike & La'An vs the Gorn. E5 was Spock Amok, Spock/T'Spring centric. E6 was a Pike ep, as the medical tech offered had to be tempting for him. But E7 he was B plot and off ship in Serene Squall. E8 was M'Benga centric. And E9 Hemmer/Uhura.
4 arguably Pike centered eps in S2, with his arc the main focus of the show.
S2 has Pike the focus in Lotus Eaters and Hegemony. Spock steals the ship in Broken Circle and the Chapel/M'benga warcangle comes in, Pelia introduced. Pike has a big role in E2, but that is all about Una (and a classic). E3 is also classic, but La'An & Kirk lead. Pike is central in Lotus Eaters. Charades is comedy and Spock centric, with Pike involved. E6 is Uhura/Hemmer. E7 is TOS and focused on the Lower Deckers. E8 is M'Benga. Mount cannot sing much so E9 was not gonna be his. But he is the focus in E10.
I thought S2 was better than S1, though it is close. The less Pike centric nature did not impact quality at all.
S3 has Pike the focus in E1. Or he is at least central. He comes up with the plan to sleep the Gorn. Hardly weak or indecisive. E2 is Spock/Corby/Chapel. E3 was pretty Pike centeic with him & M'Benga on the planet. E4 is the holodeck ep, which I thought was fantastic, BTW. Not Pike centric. E5, is not zoike centric, but also very good. E6 was classic ship battle ep. Though not Pike centric per se, Kirk is the one portrayed as indecisive here, and Pike gives him advice. E7 was the Beto doc ep. And E8 the comedy ep.
There are 2 eps left and Pike has been central to 2 of the first 8, with a big hand in another. I'd expect him to be central again in the finale, as the Patel thing has to wrap.
I do think S3 has been my least favorite so far, but the show is hardly in disarray. S1 & S2 were an extremely high bar to match. TOS couldn't put together 3 straight excellent seasons. TNG 3-6 is probably the best run. Or DS9 3-6. LD was awfully good consistently. ENT 3 & 4.
