because having shrooms that last 3 min doesnt mean that you wont step on them and it doesnt mean teemo wont place more of them, wtf are you thinking, they reduced traps duration in those maps because they are smaller, so it is easier to step on a trap, plus, if you buy it as a core item in every champ, you will most likely waste gold since you will be paying for the stealth detection but there'll be not stealth champion on the other team
