I love pvping with my Jug tbh, both tanking spec and nowdays vengeance, seriously those sages and sorcs go down pretty easily (except healers, those need few interrupts)
However, the class is really fine and better for devs to work for bigger issues (operativs/scoundrels) for example. Most of the times if we are bad in one class it prolly means it doeasnt fit us, so just pick another class, but dont generalise this like "the class sucks" cause it sure isnt.
Let devs work on more serious matters, there are other classes who have serious problems and some people here whinne about classes that work as intended.
