War: In Pvp, they just pwn everything they hit, and can take alot of damage. I always enjoy watching in observe mode how they do in GvG/HA.
Paragon: I know some will disagree but, i really do like paragon and they are great in JQ and FA. They do good damage and have support shouts which help greatly, yet doesnt seem they are that used in pvp.
Assassin: I made an assassin and loved it, in pvp i usually played my sin in. They have great attack combos, armor, and are fun both in pve/pvp. Yet in the back of my mind i wonder..."what if 1 day A-net uses the Great Nerf Hammer on them?" will they be any good after? I dont UWSC, the only SF farm i really ever did was kegging for the gold drops for title. I had an assassin before yet sadly i deleted because it had a really lame name...really lame.
So for all those war, paragon, sin lovers; Please help me choose!!!

~It would be great to state why they are superior and why you think they are better profession from the other to choose from.
