Does anyone else feel like they're being punished for buying wards?

In a lategame scenario, you have to give up something to play the game at an adequate level, assuming your team isn't shitstomping the enemy team. If you need vision, you're going have to give up a necessary active, damage, or tank stats, making you less effective than the enemy team. Not to mention that even if you have the vision, the enemy may win the fight just by virtue of having 6 items dedicated to defense or offense when you don't. You see this all the time in pro play. Supports will just not buy a 6th item and save the spot open to buy wards or pinks. Trinkets don't really solve the problem either. Even assuming everyone on your team upgrades their trinkets (which never happens, lets be honest), that means you have at most 4 warding totems and hopefully however many pinks have survived to this point, because the the support buys sightstone and the red trinket. Many junglers buy red trinket, and many assassins do as well. Now we're down to 2 warding totems, which may or may not be upgraded, and a sightstone. ADCs buy blue trinket as well. Now we're at 1 warding totem and a sightstone, assuming the enemy team doesn't have invisibility champions to counter with Oracle's, in which case you may only have the sightstone. I think it's unreasonable to have to rely on what is veritably chance on a facecheck or some line-of-sight gimmick the enemy team decides to pull because you can't have enough vision while retaining full build. I think wards should have a separate slot just like trinkets do. This would also give people something to spend gold on besides elixers, which would make me feel a lot happier because I would feel less like I'm wasting a resource.

P.S. Riot fix the charge spell bug on some routers please. I want to play Varus again ;_;
