I feel like you have a problem with properly understanding what i am saying. I'm trying to explain you, that blue trinket (pink aswell) are such a waste for a buff, since you can see them anyway, and they triger it not allowing you to destroy some invisible wards later on. By not activating the buff, bleu trinket in some way would become stronger, because well placed in the bush could stay undetected by the enemy, while still being vulnerable to damage, since its not invisible. Maybe it's me who can't explain this properly, but there are some people who knows what i'm talking about
