Sure. My point was that purely dumping everything (or almost everything) into the center would not remain the be all and end all of military strategy, and in five minutes I could design something that would beat it nine times out of ten with something even close to force parity.
Dumping all your forces in the centre isn't blobbing, though. Dumping all your forces in one region is. The blobber will always have the advantage in any particular battle. Sure, the smaller army might get lucky in the setting up of the flanks and pull off an upset, but the larger army will still have the advantage, which will encourage blobbing.
