Guild Wars 2

So right now I’m r51, been shattering the whole way. I’m a good shatterer, but my question is how do I bridge the gap to a great shatterer?

I’m running:
4,4,0,0,6: classic power shatter.
Sword/Torch: Generosity/Energy
GS: Fire/Air

Utilities:
Decoy
Blink
Mantra of Resolve

I want to learn how to six-man shatter and anything else that separate a the best from the rest. Can anyone point me to a guide or give me some tips?

Thank you! And happy holidays!

I take it you’ve seen this?
