New german TD line discussion, Three MMOs taking its toll?

GeneralDirection: Supporting a game is more than simply adding new vehicles. Whether you feel it was needed or not, a game must continue to evolve in all aspects to adopt new technologies, new user experience advancements, graphics polish, and so on. There are many things released recently that have been long-requested improvements to the game, and there are many more in development.
The German TD line, in particular, has been delayed because additional research was required. Creating a new vehicle, let alone an entire branch, is not a simple task. There is a lot of field work that has to be done, sometimes sending people to multiple states, countries, and sometimes continents to gather information on the vehicles we add. Then the work on the models and vehicle balancing begins, then it enters internal testing, then public testing, and finally the live game.
This process can take quite some time to fill out an entire branch of vehicles with viable options. It's easy to create a branch of vehicles on paper, but it's harder to actually get blueprints, measure armor thickness (if the vehicle was ever built), build accurate models in the game, and then create attributes that distinguish it  enough to where it's not exactly the same as another tier X vehicle.
