Best house rules and variants to make D&D less heroic

The reason why making boost spells based on concentration is not a nerf at all is that people will just manage to have the source of the boost spells not be on the warfield.
Ex: they pay someone to cast a bunch of boost spells and benefit all from the boost spell by turning into parasites or the boost wizard of the team stay home until he is called for wizarding out of combat.
this is why hitting the boosted person being the solution against the boost spell works better.
(special exception: missing someone with spells that makes it more easy to miss can dispel one of those spells so that someone making itself near unhittable with spells can still be defeated by attacking)

that requires preparation and hiring npcs. can be worked around, and if the players put that much effort, they should be rewarded
