take your PVE char, equip some impen gear and go out to PVP.
You don´t need a special char.
Look where the action is and go there with caution.
Always move.
When you fight, don´t forget to move.
When you´re under attack, dodge/block/shield WHILE MOVING.
When the pressure get´s to high, try to MOVE around corners.
Not moving is just the number one reason why PVP beginners have trouble.
I always run a Nord Support Warden & Necro. Aggressive group support, & control. If necessary I use the same builds in PvE (vet/norm) for my stones/gear.
