how do you want to nerv boots 1 as a starting item other than making them more expensive than 475 gold?
you nerv the speed value and it wont change ****, because every champ will be nerved by the same amount. people would still start boots 1.
and why would you even do that? how about instead of nerving everything popular, people are given alternatives instead?
for example revert parts of the dorans nervs. not completely, but enough, that they are a viable start item again. or make them really really cost effective with unique passives like prospectors blade (ring etc.) on dominion.
so they are attractive as first buy, but not stackble anymore.
