Should Passive Perception be lower?

Quote from SunIsGettingRealLow96589 >>

Using your action to attack and relying on -5 to passive perception to find someone hidden has a 25% chance of success.

 Correction: it has a 0% chance of success. Someone who's hidden has already beaten your passive perception, and there is no ability to reroll it.

Oh well, then you should like my homebrew idea then.

Battlefield Uncertainty: During combat, -5/disadvantage to passive perception.

At martial class level 5, martials get bonus action Search action. And if you take search action or bonus action, whatever you roll check results in that becomes your passive perception until the start of your next round.

So enemy hides. They rolled >15 and >your passive perception

On your turn, bonus action Search. Use all the bonuses you want to search. Heroic inspiration, bardic inspiration, luck, whatevrr. Whatever the result is, that becomes your passive perception until the start of your next turn.

I.e. find them on your bonus action, use action to attack. And on enemy's next turn, your passive is going to be substantially higher.

At martial level 10, martials are not affected by Battlefield Uncertainty, so they can get +5 advantage added to their passive perception. But can still bonus action search if they have inspiraton, luck, and so on.

Nah, I'd go with:

• Perception has disadvantage if you are currently engaged in melee.
• Perception has advantage against a creature you have targeted (with an attack or other ability) since the start of your last turn.

when you say "perception has disadvantage", then taking the search action is also at disadvantage?

I'm suggesting a modification only for passive perception. If you take the Search action, its normal, no disadvantage, and it becomes your passive perception score unti the start of your next turn. 

At the risk of muddying the waters further, if you are one to use "Degrees of Success" then a perception roll does not just mean pass/fail and passive getting the average of active probably does make less sense...

 I'd probably say "Search: when you take take the search action, you have advantage on perception rolls until the start of your next turn" and make all perception passive.
