It feels strange and interesting. Although I started playing again only a few weeks before the patch, everything feels kind of off. All the feeling for passage of time is gone and has to be relearned. But overall it gives a few more seconds of breathing room at the start of the game to set everything up.
As I am playing Zerg, the most interesting part is that with the new patch I suddenly have the option to stop spending larvae for a bit. So it is not only drone as much as possible and see what money is left an what you can afford, but actually a decision, when to build the first hatch etc.
