This game is being developed and supported by people who work on it simply because it is a game they love. You're welcome to disagree with changes, but if you're going to insult developers spending their free time working on a passion project, you stoop down to a whole new level.
Yosh's efforts has revitalized renegade more than anything since Beta 3. Before 5.1, developers have almost lost all interest. By bringing forward more strats and dealing with overpowered classes, 5.1 was the biggest step forward for RenX in months. So no, it's not going to be reverted, sadly for you. Your balance concerns about 5.1 need to be more constructive.
DoctorB0ng, who's not even involved with development, spent ridiculous hours getting himself to learn how to properly set up DDOS protected servers while everybody else backed down and surrendered while pointing fingers at each other. He was the only one willing to step up to the ddos attacks, and in the end, won. He still spends most of his time right now keeping his servers steady and running CT. He even publicly posted his methods on how to deal with the attacks so other server owners can have protect themselves too.
