PvP main focus
I like fast aggressive gameplay
also big numbers :)

Warrior, Rogue, or Mage.

Do you want 1-2 shotting? Warrior.

Do you want to never get hit and cast spells? Mage

Do you never want to lose because you can reset every fight? Rogue.

I see you are an orc

If you want to punt gnomes then the answer is Windfury!!

You will definetly have the most fun as shaman as leveling in pvp and in STV

walk on water
self heals
windfury for everyone
purge
earth shock
frost shock
chain lightning
totems
ghost wolf

Your avatar makes me think...
Warrior!
