Time isn't really getting that short though. It's still 6 months to the earliest possible release date from the current expectation assessment. It could easily be 9 months away, or they could shift the release date goalposts again.
If I were them, I'd keep those rounds in the chamber for as long as possible. On the one hand, to space out the fresh meat for the EA players, and on the other, if the game releases a little early, there could be one class that no one has touched.
