hmmm...Drums: North, Vocals: East...
Hey! no rules here...
Indeed, listen to The Beatles and you will see...
I sometimes play with phase invertions, I put a vocal track hard right and then copy it and reverse phase and pan it hard left... if you are between the two speakers, its a great effect (but no good for what may be a mono mix later).
Also try for example to record your guitar in 2 tracks, one "DIboxed" and the other with a mic. Pan one Hard L and the other hard R. Or double your guitar tracks (don't copy them, play them twice, slight variations or imperfections makes it more interesting, or try to play one track with one distortion and the other with a different one, or play open chords in 1 of them...)
If you like, try to pan the drums as you will hear them in a room, don't "overpan" unless you really want to.
Try to have the mix with a sonic balance in the final soundscape (unless you are onto Beatles stuff!) not leaving too much on one side and too little on the other...
Useful tip: Due to our Occidental nature, we seem to give a little more importance to what we hear from the left (It's not bullsh*t)
That's because we are used to read and see from left to right, so hearing has the same procedure. If two sounds are transmitted at the same intensity, at the same time, from two separate sources (speakers) you will probably hear first or a little more the one coming from the left.
So, you can pan solos or things you wanna hear a bit more "prominent" slightly left. no need to raise your volume up too much!
Peace...

NB: Gidge!!! What happened to your guitar avatar?!!
It was a classic! I could tell the post was interesting at a first glance...lol
Will have to get used to beavis and Butthead.
Cheers...
