1. Zerg doesnt need to produce offense and defense at the same time, so I dont see what the problem there is.
Zerg has to be the aggressor and expand... after doing such they can't just magically combine their offense together to make defense as a means of recovery.
Example (4 lings merging together to make a spine crawler) coming back home after having caused the opponent to (hope to god) make defense.
The queen is ultimately not cost effective with their 2 control because it is cutting in to the overall 200 control army, especially, and I mean especially not for 150 minerals.
