As a level 28 (pvp rank 20) Immo jugg I've done a lot of pvp in this chars lifespan and I don't know how you do so terribly at that level. I am getting 5-7 medals every single time. (1 kb, 2k-10k protection in 1 life, 2x defensive ones, 10 kb's, solo kill and depending on healers 75k dmg and 25 kb's.
Use your skills, I run balls and guard nodes like a boss.
