Haha, you actually favors my idea even if you not intended to.
You right, storages is kind of a substep, i don´t even thought about this, but tanky ass hell and the opponent can see them.
All Gentlemen above should´t build mass storage around mex, because of all arguments they gave 
or be at least in favor removing mass storage bonus.
- You just sit in your base and do nothing exepct eco
- you can see your opponent goes eco
- opponent can better read your base
- mapcontrol not important anymore
- just be greedy and build storages
- you don´t need to careful consider upgrading to t3
Now i´m in favor to remove the adjecency bonus for mass storages haha.
edit:
My favorite counter argument is "you don´t need to careful consider upgrading",
thats the one argument i fully agree.
