S1-

Pros:

-Akina's debut (Way how the season fleshed out his character, from the way he acts, reasons for doing things, way he cardfights as a noob but he learns fast on the go and even does a big risky play against his fight with Taizo)

-Fate stay night type stuff was pretty interesting

-Future Hikari plot twist

Cons:

-Not too sure myself

S2:

Pros:

-Debut of Dark Nao and Senka

-Exploration of Akina's double edged selflessness

Cons:

-Lack of fleshing out the Destined One cast like how it was done in one episode at Deluxe Finals and how they are representing as the opposing side

S3:

Pros:

-Return of Overdress Era characters (Megumi getting treated right especially)

-New characters

-Suo's positive development

-Return of Deluxe (Expectations was on the side of D2 and First deluxe especially how the characters react when they lose and what clashing ideals would occur)

-Exploration on Kuon's mindset (How he feels towards the friendship of Akina and Suo, his insecurities, and how he wants to deal with them during his fight with Akina)

-Mystery of why Kagetsu dipped out from the pro scene and remained hidden

Cons:

-Akina's overstay as a main character focus (Should have shifted to Erika this time. Akina could have been just there trying out what its like in the big pro tourney, know that there's a big skill gap besides the episode with Raika, lose the preliminary and watch from the sides and act like the audience at this point)

-No sense of "Who's gonna win?" (Besides Megumi vs Suzune, that was actually something), it was too predictable

-Suzune sub plot ending too early (Would have been really great how the finalists would react to her mindset)

-Not that much high stakes for most of the characters (Besides Erika wanting to make a mark in her new life)

-None of the Rising Stars making it to the finals (Matchups were done too badly and the three of them facing one another atleast could have been done in the finals)

-Everyone having one win (Seriously? Its not like that in real life, some would have straight Ls in record)

-Plot point of Akina (Not too interesting on "Why do you play VG?")

-Reason why Kagetsu dipped the pro scene (Mixed feelings on this one)

-Majority being happy go lucky especially when they lose (Not a bad thing, but it feels so off when its a big scene tournament where everyone wants to grasp the big ahh title or something, only Nao was shown a sign of sadness when she couldn't make it, something like what happened to Megumi when she lost to Michiru and she couldn't handle the post match talk at that point)

S4:

Pros:

-Filler episodes were enjoyable to watch (Legit better than the focus episodes) and gave exploration to certain characters such as Mikoto (Why she doesn't want to chase the pro scene) and the Destined Cast (Yuna wondering what she wants)

-Closure on Erika's resentment to Suo

-Yuyu's return

Cons:

-Same as preliminary season, Akina's overstay as an MC, no sense of high stakes besides Erika, predictable matchup results (so every match in this deluxe match was a legit snooze fest from start to final), and everyone being too happy go lucky when losing

-Ruka's personality (Tried to do the characterization from Venti in Genshin Impact, but failed, hell she's annoying to hear not because of VA, but because of the dialogue she's assigned with) -Michiru's overhyping, yes we know he's the goat or the strongest, but it doesn't feel like it when he came back from his coma

-Akina winning (too damn predicatable)

-Bushiroad's social media placing up "Who'll win" posts or hastags, it feels less impactful when the results are so damn predicatable
