I completely agree, having 5 people work on x and 5 work on y can be much more efficient than 10 people on x, it's a common misconception in development that increasing the number of people working on x will necessarily efficiently accelerate progress. It is very likely that the team working on these new features are independant of the team working on luke, balance, etc therefore not delaying their work. How low can the kdnf players get, they even mentionned in a recent interview it'd take them a while to find a solution to the phys/magic luke imbalance. Just like you said, it was probably in the work for a good time and they simply released it so that the small feature team can start working on something else and keep the kdnf players busy while the big feature/balance team continue to work on what's awaited. It's all "if" though, maybe the kdnf players do know how their neople is structured and it's actually a uber small team.
