Well my Shams arnt 70 yet but on the TTR i played over 100 games, figuring stuff out.

-Pally healer is BY FAR the best way you can go. No doubt i played with a 2200+ raited Pally and priest (same person) and the with the pally we won time and time again.

-EM/NS Don't blow it right away! I start off with some lightning bolts first then as a finisher do EM/NS

-2 Healers are hard, always kill one first, i found this to be a priority.

-Rouges....i....hate....lol there so gay.

Thats all i can help out for now.
Again its all about how YOU play and what you find to be the best.
More tips and comments would be nice on this setup.

Keep this up
later
