Hello awesome people!

I have a few questions about PVP, hoping some of you veterans can help out.

1. As a new PVP player (lvl 60) would it be better to craft lvl 50 PVP gear, or go in with normal lvl 60 gear until I have marks for gear?

2. Is PVP gear only for PVP (I know it probably is, but thought I'd ask)

3. Any tips for a new PVP player (heals) ? Other than follow group, heal people and use the PVP skills ?
