I'm finding that I usually get 8-10 medals per match. I've got around 360 valor (8% damage/reduction/healing) 4 pieces of Champion armor and some of the misc. pieces. However, as other classes obtain the same gear I'm finding it harder and harder to keep up damage wise. These days I'm usually close to around middle of the pack for total damage. I still win most of the one on one fights I get in, but they're getting closer. Operatives in particular are getting out of hand with the amount of damage they do out of stealth. They take so much of my HP away while I'm stunned, that by the time I can react, my DPS isn't sufficient to win the fight. It doesn't matter if I'm running a Tactics PVP spec or an Assault PVP spec.
Now, bear in mind, that I don't run with a premade. I generally don't have a healer keeping me up or anyone working with me to take or defend objectives. It does seem to me, however, that as other classes obtain PVP gear Vanguards are starting to fall behind.
