In regards to Egg Morphing, one of the things I like about it is that it makes the Xenomorphs a much bigger threat. If all it takes is one normal drone for a colony to start up, it's so much more dangerous and costly to cross paths with them.
Having everything you need to kickstart a colony being contained within either a Facehugger OR a Xenomorph makes it a very robust system, impossible to eradicate, unless you kill off every single one of them.
