Based on my impressions of Heroes of Might and Magic over the past two years, the high-roll nature of decks is its defining characteristic.
There's mid-range Dungeon, mid-range Haven, and aggro Sylvan, as well as old-school aggro Stronghold, and there was an era of neutral decks... But yes, there are many high-roll decks.
In 2019, it "suddenly" turned out that mid-range Dungeon was one of the best/most balanced decks in the history of this game.
Overall, I agree with Revan, especially in the alternate meta, this was very noticeable.
