Hey Byz. I like the article and I totally get the point around the % increase across the levels. The issue is more when you look at the actual cost and what those percentages translate into. Below is to create a modern deck, maxed to each league using low card price (credit to https://www.splintercards.com/tool-missing-bcx.html for the data)

One of the real issues I see is for gold league players. The below shows how considerable an investment it is to get to this level but gold league has 20% of the reward pool vs 15% in silver. I see no reason why a new player would ever invest $38k in a max gold deck as this will never translate into any meaningful rewards playing in gold league. Better to stay in silver. And that is a major issue.

And yes, the 80% increase to get from gold to Max is the smallest % increase but when this means an additional $30k investment, then we are still talking about an incredibly small number of players that can ever get to that point, especially if they were not here at the start where they could level up their cards at MUCH cheaper levels.

If the game is not careful it is going to be full of whales and minnows and nothing in between...
