I love finding resources like this list of Shaman tricks on the EU forums. It's little tips like these that separate the good players from the great players. You know the players I'm talking about. They're the ones who make you want to roll one of their class because they're doing such a great job. Yeah, I think they all posted on this thread.
The post is divided into three sections: general, PvP and PvE. The PvE section is further divided by raid zone. And it never hurts to show off how good you are at playing your class during a raid.
Some highlights after the jump.
