There’s no limit on the number of boots anyone can buy. How do LoL builds change?

Imagine suddenly that riot lifts the restriction of 1 boots item per character build. How would this affect character builds? You’re allowed to have 6 of the same boots as well.

Edit: there seems to be some confusion. I didn’t just mean you’re allowed to have only 6 duplicates, you can have as many duplicate boots as you want e.g. two sorcerers boots or whatever
