RTS Style Camera moves not correct after rotation

Hello, I try to make a simple camera script which can be moved with "WASD" and can be rotated with "QE".
The movement and rotation work, but when I rotate the camera the movement stays in relation to the world.

I found several examples on other ways to move the camera but I try to understand what's wrong with my way to do it.

I think there is an easy fix but I can't put my finger on it.

Here the Code:

Code (CSharp):

1. void LateUpdate()
2.     {
3.         MoveCamera();
4.         RotateCamera();
5. }
6.  
7. private void MoveCamera()
8. {
9.     float moveX = Camera.main.transform.position.x;
10.     float moveY = Camera.main.transform.position.y;
11.     float moveZ = Camera.main.transform.position.z;
12.  
13.     if(Input.GetKey( KeyCode.A))
14.     {
15.         moveX -= panSpeed * Time.deltaTime;
16.     }
17.     else if (Input.GetKey(KeyCode.D) )
18.     {
19.         moveX += panSpeed * Time.deltaTime;
20.     }
21.  
22.     if(Input.GetKey(KeyCode.W))
23.     {
24.         moveZ += panSpeed * Time.deltaTime;
25.     }
26.     else if (Input.GetKey(KeyCode.S))
27.     {
28.         moveZ -= panSpeed * Time.deltaTime;
29.  
30.     }
31.  
32.  
33.     // Zoom the camera in and out
34.     moveY = invertedMouseScroll ? moveY + Input.GetAxis("Mouse ScrollWheel") * (panSpeed): moveY - Input.GetAxis("Mouse ScrollWheel") * (panSpeed);
35.  
36.     // Clamp the Zoom Value between Min and Max Height
37.     moveY = Mathf.Clamp(moveY, minHeight, maxHeight);
38.  
39.     Vector3 newPos = new Vector3(moveX, moveY, moveZ);
40.  
41.     Camera.main.transform.position = newPos;
42.  
43. }
44.  
45.     private int RotationDirection
46.     {
47.         get
48.         {
49.             bool rotateRight = Input.GetKey( KeyCode.Q);
50.             bool rotateLeft = Input.GetKey( KeyCode.E);
51.             if (rotateLeft && rotateRight)
52.                 return 0;
53.             else if (rotateLeft && !rotateRight)
54.                 return -1;
55.             else if (!rotateLeft && rotateRight)
56.                 return 1;
57.             else
58.                 return 0;
59.         }
60.     }
61.  
62.     private void RotateCamera()
63.     {
64.         Vector3 origin = Camera.main.transform.eulerAngles;
65.         Vector3 destination = origin;
66.  
67.         if (Input.GetMouseButton(2)) // Hold midle mouse for rotate
68.         {
69.             destination.x -= Input.GetAxis("Mouse Y") * rotateAmount * Time.deltaTime;
70.             destination.y += Input.GetAxis("Mouse X") * rotateAmount * Time.deltaTime;
71.         }
72.  
73.         if (destination != origin)
74.         {
75.             Camera.main.transform.eulerAngles = Vector3.MoveTowards(origin, destination, Time.deltaTime * rotateSpeed);
76.         }
77.  
78.         transform.Rotate(Vector3.up, RotationDirection * Time.deltaTime * rotateSpeed, Space.World);
79.  
80.     }
81.  

Any tips or comments on how I can change this to work correctly?

I already saw that.

1. Did you mean something like this?

Code (CSharp):

1.  newPos = transform.InverseTransformDirection(Vector3.forward);
2.  

The Camera is not moving after this, and the rotation is broken. Any Ideas why?

Option 2 is not the way i want to do this. I want to be able to change the moving keys in a later state of the project.
