They have added a significant amount of "waste" when using the focus feature. Rather than transferring the full 25%, you only produce a fraction of the 25% when using focus. Perhaps this is good new for you. It is a little harder to use now.
But, and there is a but, with a few alterations to the strategy, I've been able to modify the approach to win with both all labs and all factories. In fact, depending on the race tree you have access to, I've found it even easier in TA.
To give you peace of mind, I won't tell you how I altered the strategy. Now you should have no problem playing how you like...
And really, you should buy TA anyway.
