Pretty much as the title says. I'm not very experienced in pvp yet, I was running light armor for leveling/questing and only after hitting VR rank 4 did I get around to comparing defense values. I wasn't aware spell resist was increased with a 1:1 ratio to your armor value which pretty much dumbfounded me. Anyway, does anyone have experience using it in pvp? What tactics do you use to overcome the massive decrease in survivability? Running solo is obviously never a wise choice in pvp, but how big of a group would you need to be running with to really reap the benefits of the light armor passives?
