The state of control wards
Control wards have 3 functions: Being a permanent ward, disabling and allowing the destruction of enemy wards and granting vision on invisible enemy champions. Their downsides are the fact that they're visible and the 30 gold reward they give. Most of the times they're destroyed within 1 minute of being placed since their warding locations are the exact same as every other ward, making it a waste of 75 gold (more than half a Faerie Charm) and free 30 gold to the enemy. With everyone starting the game with a trinket that grants 2 wards for free and the supports getting 4 rechargeable wards around the 10 minute mark, the control wards' vision is simply outclassed. The blue trinket allows the placement of a permanent ward up to 4000 units away from the caster, allowing for safe warding and granting only half the bounty control wards give, the main downside being that they too are not invisible and require level 9. The red trinket allows the user to see invisible units for 10 seconds, allowing easy dewarding and the possibility of dewarding multiple wards with one use since it follows you, the main downside being that you lose the ability to place the trinket wards. While normal wards can grant vision multiple times until they time out, control wards are destroyed the moment they're seen, making them inefficient. Control wards are useful in two scenarios: Revealing if the enemy team is about to do baron/dragon(and even then, the blue trinket does it even better since it allows you to see the area without being there) and giving vision so you can see eve/shaco ganking you. With all that and considering that as a support you have to pay 75 gold to give 30 to your enemy team, i don't see why control wards are bought at all. I could kind of see why a jungler/top laner would buy them to reveal the baron/dragon pit but it's mostly supports and ADCs that buy them for the river bushes. As a support main, i get an average of 120 gold per lane phase from people putting control wards on the bot lane's river bush, that gold allows me to reach redemption about a minute before i would normally.
With all that i ask you, what do you think of control wards the way they are at the moment? I personally believe they need a buff to actually be worth the 75 gold and the risk of a 30 gold reward, making them invisible would certainly make them worth it.
