Sightstone
So, my boyfriend doesn't think it's necessary to buy sightstone as a support. Simply because, "Everyone has wards. I have my standard wards and so does my ADC. It's pointless to waste 800 gold on sightstone when everyone has wards." What do I do? I've tried everything to convince him that he should buy sightstone. I don't know what else to say/do. Suggestions?

aren't that bad if he really wants to build selfish items
