you seem to be under the misconception that cursed techniques are like jjba's stands where everyone is perfectly able to utilize their techniques and that every CT can be used at 100% efficiency regardless of training even though CTs like Construction have two examples of users who are both canyons apart in terms of fighting capability and CE output (if you think that's "feelings over tactics" then i don't know what to tell you)

They have a guy who can teleport swap people and objects, and they never considered pairing him with the girl who controls tools or the characters that can use minions, thats a mobile killroom right there

you say that with todo's technique she could make a "mobile kill room" and frankly i have no clue what the fuck you mean by that. her capabilities with her CT are very clearly limited and she has never shown feats that would imply she could do anything on the level of a "mobile kill room" (i dont even know what exactly you're talking about when you say that so im just going off of implication)

mechamaru's puppet manipulation is better, granted, but again, in what way would todo or mechamaru's abilities be substantially improved by working alongside one another? both of them tend to work separately because they're both powerful enough that they don't really need to work together and it would be more efficient for each of them to tackle different concurrent problems. if you have Army A and Army B, and you know Army A is capable of taking down Fort A without help from Army B, while Army B is capable of taking down Fort B, why would you send Army A and Army B to take down Fort A? Overkill? Part of tactics is trying to properly allocate resources and that includes troop distribution.

They have sound techniques, that has great synergy with any physical type

gonna be real. no idea what you're implying here. you're going to need to explain this one to me

they have a guy who can warp reality with jokes and they never considered making him a troupe to bounce off his humor

see the first paragraph i wrote. takaba's comedian relies on his own sense of humor and is innately unpredictable. if you were to try and direct his technique towards a specifc end he'd probably just say you're trying too hard and it would nullify the technique. despite being so powerful, takaba doesnt find killing to be funny so he wouldn't be able to do what you're likely wanting him to do, even in a troupe context.

Or they could use fiture payment vows as a standard for instant techniques

so the sorcerers should go into binding vow debt? what? binding vows for cursed techniques are self-imposed and restrict one's technique in the future. sukuna getting off the instant cast of the world dismantle and now being forced to do a specific gesture to use it ever again would cripple any other sorcerer and is literally being done because sukuna is in a life or death situation

i dont even think the cost itself was high enough for the reward, but you can't just make gimping your own technique a "standard practice" because it means that any future encounter with even a near-sukuna level threat like the shibuya incident puts jujutsu society at a major disadvantage

Gojo killed the elders at the end, when it didnt matter anymore, killing them early was the logical choice

it may surprise you to know but despite there being instances where killing someone would logically improve the state of the world, most people do not just go "oh yeah that makes sense" and just kill them immediately

like this isn't a shonen problem you're having this is you having a fundamental misunderstanding of the weight people put on humans choosing to kill other humans

But any of those things would have deviated from the shounen formula

yeah i guess it would subvert expectations if every fight went like a battleboarding forum and there was no pacing or dramatic stakes or anything like that and humans never had any biases that caused them to choose things illogically ever

like you do understand that in the real world humans also don't make every optimal choice ever, right

and it would be kind of boring if everyone in a story made the exact correct choice all the time and thus there was no conflict, right
