Just my 2cents

1.Chain lightning looks great bouncing through a crowd and does a great job of pissing off the other faction :whistling:

2. shamans wear mail so more survivability

3. Have the ability to heal and rez

4.Awesome buffs from totems both for a x5 group or pvp raid

5. Have a knock back ability to get out of trouble (Thunderstorm x5 on round robin)

6. Elemental Mastery and Blood Fury x5 focus fire = NUKE

and finally,
CUZ TH@Y R PWWWNZNZZZZSOR~!!!!oNE!

Sorry had to do it. :thumbsup: Serously hope that sheds some light.
Just my 2 cents,
