I am in the same situation. I have a 4-shammy/pally team on pve and a 5 druid team on a pvp realm. This was actually my first try on pvp and I like it. ATM I cant see myself liking pvp without a stealth class. My first world kill was at lvl 31....I actaully killed a hunter who tried to gank me. lol.

I like my duid team more though. It seems more powerfull and moonkin form rocks. Shammies are in the mid 70s so they are my first priorty atm.
