I haven't played the beta so I'm not going to comment on balance because I'm not retarded.
However, I really can't see why people are complaining about workers automatically being sent to mineral patches and a display for worker saturation. Completely ignoring the fact that you really want around 16 workers on your minerals, not the recommended 24, it really shouldn't have an impact on competitive play.
There's always the argument that people accidentally sending too many workers to gas (looking at you, IdrA) though when you're shitting bricks in the middle of an engagement, you aren't necessarily looking at the x/24 and x/3 display.
Furthermore, workers auto-rallying at the start means nothing. There's a number-crunching thread on TL from ages ago that demonstrates that moving them all to 1 patch is just as money-efficient as splitting them manually. There is literally nothing negative about this addition.
I'd be inclined to think that people who're pissing the bed over these tiny changes are simply looking for a reason to criticise the game. If you are actually going to complain about something, at least jump on the unit balance whinge-train because there's actually a sliver of substance to those arguments.
