If the support isn't warding, and the carry has to, then that means the carry is already behind. It's better for them to talk to the support and get them to ward than acctually buy wards themselves. Heck, when I (as a support) see my carry buying wards in the laning phase, I tell them to please stop; and that I have wards covered. Then I say I'm sorry if I'm not warding well enough for their taste, and ask them where they'd like me to ward. If I have to buy more wards to make them feel safe and it puts off my build, so be it. Their build is more important.
Unless your support is a total boss, it's worth it to have 1 ward on you.
I'm not saying always, but as AD, when you back and you see that your support is out of wards, just grab one (if you have the spare money).
I mean, I started Boots + 3HP.
And I have to back. I have enough for BF sword, Vamp scepter and I have 200 gold left over.
I see my support doesn't have wards left, I buy 1...maybe 2.
It's not an issue of my support player being inadequate, it's an issue of fluidness of gameplay. There might be that moment where you don't have coverage, so you gotta get it covered while your support is back and buying. That's a solid 30 seconds or so where you could be out vision.
Additionally, I've run up against players who will zone the support to prevent them from warding. Want to drop a ward in river? Too bad, Leona/Corki is always in position to jump your support the moment they go to ward. The AD has more attack range and can time their abilities and movement better. It's the same reason that the AD takes Heal rather than the support. Because the AD knows when he needs it, and they can press that "oh ****" button when they need it rather than having to let someone else control it. Same principle. Some times, it's just really hard for the support to get to the correct position to ward against an aggressive lane.
