Isnt that the approach that keeps blobbing viable? I mean, if we follow you logic the only viable counter to blibbing would be a counterblob.
No.
The point is that the only way to properly counter an enemy force is to have at least a comparable investment into that fight.
If my opponent has nothing but one MG on the point, spending a few minutes delicately arranging my entire army just to kill it is wasted time. I have enough firepower to wipe it out, may as well punch it in the face, get capping and move on.
But so long as your force is at least half of your opponent's, a well micored force will always counter a blob. Two overlapping MG's and a little supporting infantry is a big ol' middle finger to infantry blobs all day every day.
