Back when the devs introduced the unit cap they said it was to make Gwent matches to feel more like a battlefield - with armies (or at least squads) fighting with special cards and artifacts supporting them.
But the unitless decks problem persists. Since you mostly play 10-15 cards in a game, the majority of them can still be non-units (tutors making it even easier). Introducing Maduk to add extra value to bombs and Eldain to boost traps tilts the balance too.
And while low-unit decks are valid in terms of current deckbuilding limits, I see them as pretty boring and annoying to play against. Moreso, I think they damage the skill of people playing them.
Back in three-row Gwent there were strict limits for Gold (1) and Silver (3) cards, so you had to make them count. Maybe non-units should be limited by 5, for example? Of course, this implies serious balance changes, but Gwent needs them anyway.
