Sorry, I dont mean rotation around the player, I mean the vertical angle, so approaching top down camera. As it is, its parallel with the terrain, which can cause visibility issues if the player is on a hill for example. I hope this screenshot helps. As you can see(or well, cant see), the player model is behind this tree stump and I am unable to rotate the camera on the Y axis to regain visual. Yes, I could rotate around on the X axis in this case, but not having Y axis rotation removes player freedom in a way that can take the player out of the game when they're focusing more on controlling the camera instead of enjoying the game.
Sorry if this still wasnt clear :(
