need some shaman pvp advice!Follow

Hi everyone ! ^^ I am a balance druid and my sister is a shaman troll.

We are both a team and we like to do alot of battlegrounds together.

I wish to ask is ..

Does shaman get any CC spells? cos my plan so far is me to root one person and me and my sister attack the other person . But this is hard since she hasnt got any CC spells yet.

How should she spec?
which is best for pvp?
and which is best for being in a team with a druid?

Also what stats should she focus on ? thanks for your time ^^
