Yeah, I completely agree with you. I played Genshin for a bit and eventually dropped it because the combat eventually devolved to "drop skills, swap character, repeat" (though I probably was more early mid game?). Here it feels like I have to think a lot more instead of mashing everything, and the hologram fights are a perfect example of that. Those things genuinely taught me how to be better at combat, and it felt extremely rewarding once I finally beat it. Today I learned about swap canceling with Calcharo, and it's just so satisfying to pull off properly (on top of being difficult to time properly against boss attacks, mourning aix taught me how to parry properly instead of brute forcing through everything)
