Some random thoughts that influence the decicion:
-In 1v1, mass storage don't appear for a long time, but the factory bonus you get at once. If the game is close, and you feel like you will need any unit, you attach the factory to mex.
-If you tech your factory, you get more bonus, that can be more then a storage would give. But the storage mass bonus you can invest in anything, the factory one only in units of the factory. So for higher tech factories, storage is more flexible, factory attached more powerfull.
-The factories you don't tech, you can reclaim later, and still make storage, while profiting from the early attachment boost.
-You often have more mex then factories, so it will be late until you run out of mex that you can't surround with storage, even if you attach factories to mex.
-Clumping 4 facs together arround a mex can make pathfinding troubles, and make the mex not reachable with engies.
-Sometimes the mex is not at the position that would be good for the factory
So summarized, i'd say if you fight a lot early (1v1 usually) it is always good to attach factories to mex, unless you think the factory is not well placed there. If you don't really fight much early, and make eco (teamgames usually), it can still be good for higher tech factories, but you lose flexibility.Statistics: Posted by Zock — 12 Oct 2013, 16:02
