It's lvl 40 valor, not lvl 40 Sith Inquisitor. I'd have to pvp for 14 more valor levels before I could buy ranked comms. : /
But ah well. I'll just hold out on pvp for another, oh, 17 levels? Then I'll be able to buy me gear.
If your valor isn't capped every level then...
Well, I guess you could buy a valor boost off the CM. Buy medpacks in the meantime.
