I see like 3 other threads...

There are like 3 other threads immediately about the exact thing... and I feel like people would benefit greatly from reading your post AND the teamliquid one.  I don't want to be pretentious though and just copy and paste the link- or possibly be insulting.  

My MMR has semi-balanced out.  I'm winning about half my matches now, and my biggest enemies include siege tanks and banelings.  Some guy made an armada of bainshees, tanks, rines, marauders, and medivacs... and he just absolutely schooled me!  I suppose the better players are still going to defeat me no problem- but it's not about winning right now.

Right now it's all about getting to a point with this macro that I don't even think anymore.
