After a long time playing Protoss I changed for Zerg.
The first thing is that all just fun again. Sliding from Platinum to Silver. Don´t care :)
The second thing is that Zerg seems to have much more options. I can rush zerglings, zerglings with speed, banneling, or crazy expand, or go heavy roaches.
The third thing is that hard learn the timing and when produce drones. I died many games with 1500 minerals in the banking.
The forth thing is that Protoss die a lot if you attack with a bunch of lings in the beginning, even if they wall with 1 or 2 zealots.
The fifth is that I suck a lot in the game and suck even bad against Terran. They wall with siege tanks and bankers, circle the main with turrets and kill my army with a strong push while 2 dropships kill my entire base.
