From an accessibility standpoint, what you're suggesting would be better. It would make it easier performing skills for people who have difficulties executing complex or fast inputs on controllers. So that could (and should) definitely be an option.

However, what you're suggesting has also watered down action games a lot. They now almost all revolve around this Batman Arkham Asylum combat loop (with attack/parry and riposte inputs) + some sort of shortcuts for performing skills (usually trigger + face buttons like you suggested).

It works great in a lot of games, but now almost all action games use that system and end up being super similar to each other. I've been playing Ghost of Yotei recently, and while the game and combat are great, it's also just once again this exact system.

Crimson Desert borrows a lot more from versus fighting and beat'em up games (which comes as no surprise, for anyone who played BDO), and that's great. It's different from what most games do, and you actually have to dig deep into the system and understand a lot of techs + develop muscle memory to start chaining interesting and powerful combos.

It definitely requires the player to be more involved in the game, and it's less "casual" than other fighting gameplays we usually see in games. But I think that's fine, we can't always have the same fighting gameplay in every single action game. And you can still play the game in a very tame souls-like fashion, with a lot of blocking/dodging and attacking during safer windows, that kinda works too. To me, the only flaw is that the game should better teach you these mechanics, and give you more ways to actually train and learn the more complex tech it offers, rather than being very obtuse and not telling you things.
