It's not that hard for me to understand that the Dev's need to pay bills and I for one like the DLC ships. I don't think they are to OP. Have seen the Herc and Req both die in fires more than once and have also seen people kill others with just a snow. If it was really OP you would see a lot more of them. It's a great way for people that might only have an hour or two a day to play to jump on and enjoy the game.
