You can plan for comps by looking at what your opponents have, how they're all positioning and what items they have.
You can plan, but only statistically, and it's a pretty wide statistics (ie. RNG). Positioning means nothing, since you have 7-6-5-4.. random opponents.
And when you get to the final duels, you cannot change your comp anymore; just minor changes in positioning, indeed, but since your opponent will likely do the same, and will move his troops until the very last second, it's still random.
Early looking can make a difference as to planning what comp you go and what you deny. Taking Aatroxes and Kennens out of the pool and holding onto them can deny power spikes for instance and even force them off of comps
Yes, and still your actual composition will be strongly influenced by the cards you get.
You can have some partial influence, but it's indeed very partial.
If you see a lot of folks using Assassins, you know to shift your positioning so your backline is protected, if you see a lot of glacials, you space them out, if demons, you put your least relevant unit to the front as bait. You plan against the majority and tech against the others later.
No, it doesn't work this way: you space your guys in order to face glacials, and you randomly get an assassin opponent. Or vice versa.
You can "plan against the majority", but it's still gambling in a major portion.
Plus, don't forget that some combinations (Knights..) are awful, and other ones are broken. So you still are compelled to look for busted champs no matter what, and to skip others no matter what.
(anyway, RNG- based still doesn't mean you can play it blindfolded :P)
