The myth that season 4 was an underpopulated season is fake news. Season 1 was the most underpopulated by far. Additionally, its why everyone seems to know about season 1 but have no idea about season 1. It was Season 2 that people started actually using arena and Season 3 that it really kicked into gear.
Also note there’s a significant difference in the data versus the representation of classes for Season 1 and 2 specifically. Most people didn’t play in this era of really low resilience and overall arena participation which is why the numbers are very different.
The season 3 and 4 numbers are what we are used to seeing. The only true anomaly that could change before then and now are hunters. In a world that had keyboard turning clickers, the hunter was the only class so incredibly punished by this and was reflected in representation numbers despite being a very popular class for PvE. This isn’t the case in 2021.
