I"ve never doubted blender’s ability to create a complicated mesh, as in the hands of the right person, nearly any 3d app can do that, basically ( for them) chlids play.
I dont want to ‘gloss over’ the importance though of what I said about blender edit mode stopping me in my tracks from using blender at all on my current mesh 
Thats important too , and it should be a clear signal to blender devs that until its fixed, they are losing alot of customers , and my abiity to make use of open source free software.
