Shadow Warlock Rotation

I'm not sure if there's a set rotation but I know that for shadow during SB you just spam RMB and 4 and include a LMB for the focus regen. but when I'm out of SB I have no idea what sorta rotation i need to be doing atm I just press V on CD RMB, F, RMB, 4 and rinse and repeat I'll also include a 2 and F aswell as a 3 ever so often but my dps just sorta drops off when i get out of SB so I know I'm doing something wrong. Thanks for the responses in advance.
