Didn't Machine Guns get buffed against blobs recently or am I mistaken?
In the last patch? No. They only buffed the MG42 damage.
It was already clear from the patch notes that there will not change much about blobbing. The only blob that got nerfed was the OKW one, but they often continue blobbing because they have not much choice anyway. In fact as was already said they might blob even more now because they need more infantry to get as much done as the old blobs. On the other hand they buffed PTRS so that Soviets have more effective infantry that might get blobbed.
In terms of anti-blob weapons they did not do much either. leIG still won't stop blobs besides the suppression buff, you would need multiple ones but they cost a lot, USF Mortar Halftrack still does not see much use apparently, and I think that was already it in terms of improved anti blob weapons.
But I assume this issue will be addressed to some degree again in the next patch
