Make ANY semi-decent comp and preferably get the best resto shaman you know on the opposition team.
Now all game your goal is to tunnel that shaman, you can ofc peel their cooldowns as usual but once they're gone, get right back onto that tunnel target.
Follow every decent stun you have with a silence. Just for the lols follow that silence with more silences or stuns if you have them.
Then come back and tell me how long they lasted and how amazingly skillful you had to play to earn that victory.
