You don't get tired of seeing one monster's decent hide check opposed by 5 players' (and sometimes their pets') wildly-randomized spot checks? Or similar results on a bluff/insight check. Or an opposed intelligence check.
I don't.
The more eyes and ears trying to find something, whether in game or in life, the more likely it is to be spotted.
Hiding from a group of alert adventurers in anywhere near melee range should be spectacularly difficult.
