The dev said they won't release any new carrier or sell any premium carrier before the rework, I don't expect the rework would be soon, because it's not like just releasing a new line of ships, it changes the entire game mechanics of AA and Aircraft control. UK carrier would be interesting since the bris probably ranked third when it comes to quantity in ww2(correct me if I'm wrong)
I dont think it have this kind of service for every players. I do have a friend which had a pretty screw up name of "sex_with_me_sex". Few months later, the game offered a rename chance for him, for his ... inappropriate name. But like I dont think your name is offensive enough to be given a rename opportunity. Sorry to disappoint you.
