Make trinkets cost gold

This is just for discussion and I am not declaring this is be some solution to any problem. Just food for thought. Here is my proposition: Lets make trinkets cost gold. Trinkets themselves are still free; as in they will regenerate to give you a free ward/sweeper/scrying effect. But, during that regeneration process or cooldown duration of the next trinket, you are able to purchase a ward/sweeper/scrying to use immediately.

Lets take a look at the current versions of the trinkets: Warding Totem: Stores one charge every 240 - 120 (based on level) seconds, up to 2 maximum charges Sweeping Lens: Summons a Sweeper Drone that escorts you for the next 10 seconds (90 - 60 (based on level) second cooldown).

Here are my versions(again this is hypothetical and just for the purpose of "What if trinkets cost gold") : Warding Totem: Stores one charge every 180 seconds, up to 2 maximum charges Sweeping Lens: Summons a Sweeper Drone that escorts you for the next 10 seconds (90 second cooldown).

Trinkets(warding/sweeping/scrying): Cost 100g (Pricing is imaginary)

As i currently see the game. Obtaining vision is completely free, in the sense that you don't need to spend any amount of gold to get it. I am not neglecting that pink wards exist and need to be purchased with gold(75g), but you don't need to purchase a pink ward to obtain vision in the game. The game freely gives you vision with trinkets. There is not a lot of risk or investment into obtaining vision for your team or yourself. Presently, the only risk I can think of when obtaining vision is the potential of the enemy waiting for you to face check fog of war resulting in death or getting seriously injured. That does sound like a very large risk, however those happen very infrequently and far between your standard summoner's rift matches. The payout if the ward is placed and you get a good amount of information from it is immense, from no cost to you either, just the cooldown time of your next trinket

I propose that having the ability to purchase trinkets gives you a lot more risk for providing more potential payoff for your team and yourself. Because when you buy a trinket, you are exposed to the same risk as before but adding on the investment in gold and the potential of that investment to go badly(as in that 100g trinket i just bought got destroyed after placing it...that was awful). But when it is a good investment, then overall, you can't go wrong just like if the trinket were free all the time. It gives initiative or a decision for players to either invest their money into getting vision or getting items.

How would buying a trinket even work? Simple enough, if you have a Warding Totem with available slots(max of 2) and is on cooldown, you are able to purchase 1 warding totem for 100g Same for Sweeping Lens and Scrying Orb, if they are on cooldown, you are able to purchase them for 100g When purchasing, the cooldown duration of the next trinket is reset back to the maximum amount.
