PvP is fine. PvP is fun. If you're complaining it's probably because you're losing, which means you'll only stop complaining once you start winning.I gather from the fact that you would rather QQ about losing than try to improve and start winning shows that you'll only be happy when your main is buffed and everyone else gets nerfed into creamy dust, allowing you to taste winning. This is not going to happen. I would try to stop QQing if I were you.
No game is perfect. No game is perfectly balanced. Do you really want to live in a Star World where all classes have the same dps/healing/tanking capabilities? Where every damage record for every class is 2.35 million across the board? Picture endless perfectly even warzones filled with easily interchangeable team structures, none better than the last. Soon all outfits blend, leaving a single, balanced, endless entity. And there will finally be peace in the Galaxy. All because someone QQed a little because they were losing, and not winning.
