I never really got into pvp. I have only jumped into the war zones a few times. My Sentinel is now level 35 and I have no pvp gear. I want to get into doing more pvp, so should I jump into some war zones and get more commendations for some gear? Should I level up to 40 and get level 40 gear instead of level 20 gear? And like the title says, do I use pvp gear all the time even when not playing pvp?
