Hi , I´m @trenloco.
If I had to choose, I would rework tournaments entirely. As a new-ish player, with a modest card collection, I avoid events like the plague.
Even with novice level caps, battles feel meaningless. The prizes are always very skewed toward the top positions (as expected) and those are almost always taken by whales, with access to the whole card pool.
I´d suggest some kind of draft or fixed pool tournament, where new players can enter and really test out their skills, without fearing of losing to cheese like Kron/Llama or stacked Yodin decks at novice cap.
