Making relationships more effective and not settling for good vs great

I understand the difference of taking and having full responsibility vs asking others to fulfill your needs, but doesn’t other skills like communication skills, knowing love languages, and other types of relationship building skills just make relationships easier to have. If we are not building skills or simply stating “this is my love language” (without expectations) telling our partners ways in which they could make the relationship flourish, how is it ever going to get above baseline. It just sounds like settling for good when you can have great, but without communication and verbalizing these things (even without expectation) to your partner, it could never get there. I am not expecting what they do to bring me happiness, what I am saying is It could be flourishing instead of being neutral through communication.
