I asked about this on the PvP forums and didn't get an adequate answer.
Are you claiming this because you know for sure? Or you just think so?
I've been thinking about getting into PvP. When I swap my PvE gear for recruit I lose 35% of my health and 25% of my dps. My instinct is to keep my PvE gear and grind Battlemaster and don't even bother with Recruit. I've had 3 people disagree with me, but nobody has given any concrete explanation.
Experimented with this myself. I'm almost full augmented black hole for pve and complete augmented war hero for pvp. I put on all my black hole gear (21k hp, 2200 willpower) and entered a warzone. I thought I got melted fast with my war hero gear! It was so much worse with black hole. I know this isn't a campaign vs recruit comparison but it still goes to show how fast you can melt in PVP even with high end gear on. Go with the recruit gear. At least then your healers will take the time to try to keep you alive. When I see a zero expertise, 25k anything in my warzones I don't bother wasting my force to heal them.
