There should be a feature that we can transform a hero, for example, Serra, a rare, into higher ranks, like unique hero. It should ask lots of resources, drops etc. But in the end-game, hardly achieved within time-gated requirements, but we should be able to transform low rarity heroes.
I look at Seera for example. Love it. Healing hero. Protects. Fast charge speed. Alchemist etc. It turns out with “hero power charms” game, the gap between a rare and a unique hero gets toooo high.
70% of heroes are not unique or legendary. This means the game loses its great content and value of 70% of heroes at mid-end game. The game can totally boost their rich hero roster x3-x4 times by getting all their heroes into play.
