Superscout is really great, I agree. I wouldn’t say it’s always needed though. And I defo wouldn’t call a captain bad for not having it… Basically, it depends on what your team wants to do.
Vision is useful in a macro sense because you can use the map information to poach camps and out-resource/split-push the enemy team. It’s also good defensively to help avoid ganks. But if your team isn’t going to invade or rotate opportunistically to apply pressure, and the enemy team is playing the lane game too, then Superscout is largely wasted. I think your money would be better spent on an early offensive item, honestly, like a weapon blade or stormguard banner so you can apply more pressure Maybe even upgrade these to tension bow or stormcrown. If you apply pressure, the enemy will have to deal with you, negating your need for vision (other than a couple warning cams) because you’ll know where they are. If you’re not applying pressure, the enemy can saunter any old place, and you won’t know where they are, which is when you need the vision. But then, if you’re not applying pressure, what do you really need the vision for? Just keep playing defensively.
I can see where Superscout is core like Fountain in an invade meta, with coordinated teams and a public player pool that’s on the same page, which is sort of where high-tier is at right now, but I’m not sure it’s always needed quite yet. Definitely not across the tiers.
