I feel having Sightstone provide any less than 2 wards at a time would cost supports more gold, and I would honestly rather keep the current build. You kind of need a minimum of two wards active at a time - so going back and spending 400g on 1 ward and still needing 75-225g to buy some extra wards defeats the purpose of this change. You may as well just spend 475g on a Ruby Crystal and ask your ADC to please buy 1 or 2 early wards (from my experience, most ADC aren't dicks - although I've come to appreciate I'm one of the lucky ones).
