I'm going to have to play this build to get a real idea of how it is, but from reading this, I'm not sure I like the direction Aliens are going. If the gorge can build off of infestation, why have it spread to walls and ceilings anyway? It will just be used for commander's buildings. Now marines stepping on infestation will not get seen by the commander? Removing mini-cysts and improving belly slide?
Be honest guys, did you intend to turn the Gorge into a battle-engie/medic mix? Or did it just come out that way? The Gorge has gotten more and more useless as a defender recently, are you intentionally placing all the effort of defensive construction on the commander and his whips?
