Play a different class. I played sentinal for pvp and was terrible at it. And guess what? It wasnt because others were OP, it was because I was a shi**y sentinal player. Now I play Vanguard and love it. Sadly I will no longer get any more laughs after pulling the opposing ball carrier into the spawn area in huttball.
My point: play a character you are good at and stop crying.
