I also don't know whats all that fuss about. I enjoy playing my Scoundrel in pvp more every day as my gear gets better (currently 3 pieces centurion/whatsitcalled). I think this has something to do with my expectations.
I don't expect to be able to sneak behind enemy lines, pick one, roflstomp him and vanish again before they even notice. I also don't expect to be healable if I waltz into a crowd and dish out all I've got.
It's simple: stick with your team, avoid focus of enemy players and you will be a great asset in any warzone(well, except Huttball. I leave those cause it's no fun to be the only one who can't push enemies into the pit or jump out of it).
Edit: Never roll a class because they are the fotm in a mmo. You knew this was coming so stop bîtching about it.
