User blog comment:Big Lupu/Why do wards take slots?/@comment-6003864-20130609134056

Well then don't get sightstone :P If you feel it's taking up space, buy individual wards as they are needed and just build your other items as they are. And if you're running out of item space as the support, someone on your team is derping hardcore because that means your entire team should have full builds and you should either be locked up in your base (which means wards are limited use-wise anyway), or knocking down inhibitors like cardboard (in which case you won't need to worry about ward except maybe at Baron)
