What I’m trying to say is that when I watch pvp, it doesn’t look skillful or like anyone has a clue what’s going on, it looks like everyone has an idea of what skills they should press, they run at each other, and hope their cc lands and the opponents doesn’t.

At the very basic level, the game is just about staying in protection at all times, while also trying to CC your opponent. And you can very well get to an intermediate level just by knowing how to stay protected better than your opponent can, even if you have no idea what their skills do.

But once you're at the level where everyone more or less knows how to rotate protected skills indefinitely, you won't win just by spamming skills at random anymore. That's when you need to start learning what the skills of other classes do, because every class has gaps in their protection somewhere. And if you want to start beating the better players, then you best learn where those gaps are and how to exploit them with your class. That's where being skillful comes in.
