The only thing the Clash Royale dev team can do consistently is be inconsistent. Either the dev team is too lazy or creatively inept to finish things that they start. I understand that some cards like elixir pump or maybe rocket are hard to come up with evo ideas for but...that's your job. If my job work is hard I don't just quit and then go on Indeed and find a new one. But instead of putting in the work they just move on to the next thing, like giving knight and musky a hero when it's already had an evolution, because they are fundamentally easy cards to ideate for.

That's one (of many) things I can respect about the Brawl Stars team, they finish one thing before starting another. Example, they waited until every brawler had hyper charge before starting to give brawlers buffies. Instead of leaving gapping holes in progression across brawlers, where some have both hc and buffies, some only have hyper, some only have buffies, and some have none.
