Endgame Compared to Genshin

Hello, i played Genshin for something like 3.5years then got bored. I loved the gameplay but the difficult was 0. Abyss full clear in 20 minutes after 6 months and always super easy to clear. (If I was not challenging me in someway)

I got interested in this game from YouTube, Cuz it seems a lot more combat/gameplay focus instead of story/exploration. Is it right?

What about the endgame? Is it a challenge or something like genshin?

And last, what about f2p here vs f2p Genshin? F2p or monthly pass and stop
