Can oracle's elixir last for a shorter duration in ARAM?

5, persistent in death, minutes is a very long time to have vision of any and all traps for just a messily 300g. It completely shuts down Teemo 100% since you have to be stupid to walk on his shrooms when you reveal them. Shaco is semi affected too, but usually the box goes off anyways and cant be cleared by melee champions without them taking some damage. Sure and exist too, but no one wants to sacrifice a build item slot for them. is a buy and forget buff which persists through death If they can use 1 potion to completely shut down a champion's ult , they should have to buy it often and it should be costly.

How about that it lasts for 2-2.5 minutes and is lost after dying twice regardless of time remaining.
