All my toons are on JC, and I PvP all the time when I'm on there. The pubs almost always are on a losing streak, I try to help them with my jedi guardian who is on the vigilance spec, and still can't win because the scoundrels are either not capping the pylons, the other tanks don't grab the ball in huttball and don't communicate, don't stop people from capping the turrets in alderran scenario, or don't cap to begin with; and lastly, don't call incs. Yeah, sometimes it's balanced, but most of the time the pubs are losing and I decide to to hop on my hatred assassin as she is very good at causing a distraction for the healers and dps, and of course, she is good at dealing tons of damage.
