Complete if it isn't luck but the drops are all luck. You get them regardless of skill or number of completes. Hard work and video game shouldn't be said together and it's not work if the drop is luck. Lastly, why wait to quit, the model will be the exact same with the next dlc. Up the lvl, make old raid gear obsolete (basically) sell new gear and reward hard raid gear. Grind and go again. You obviously don't like the game. Why continue to play.
