Sightstones aren't mandatory for support role.
I'm a Zyra support main (or at least, I was) and I have a free ward every 20-10s. Not gonna waste my gold on an item that doesn't even make half of that effect. Y'know that free thing everyone buys at the beginning? The combined effects of both totems (adc and support's totems) makes that effect for free. I often buy two pink wards for the vision and that's perfectly fine. Shut ur trap about sight stones and play.

). It also allows you to pick up one of these bad boys
to help get rid of enemy wards while you can still place wards. Honestly this thread sounds more like an excuse for you to build full damage as a "Support". Note: this is all from the views of a support main.
