Well supports buy SightStone. To place good Sight wards and to clear good wards, you have to be away from your laners and be away from providing them with your utility (defensively or offensively). Mobi boots don't break while attacking wards and allow you to react to map advantages when your allies need help. And supports need to walk arguably everywhere and a lot to get their wards down, or to break enemy vision lines.
