It’s worth to talk a little more but basically…
It’s a decent part of it.
People very often exagerate in the number of things they want to change but if you touch key pieces you usually get a better result.
I not promise that it will solve literally everything but it’s a decent step towards the objective.
As for liking lightshow or not…
The deck literally dies at the adittion of more mage spells to standard.
People can live with it for 2 months.
I can’t conceive that people literally want a stale metagame over a healthier one just because they don’t like a deck.
