The problem with blobbing currently is that not all factions have good counters to it, whether it's disappointing MGs that don't suppress/group suppress or lack of rocket arty.
Every single faction has HMG.
HMGs are more effective, the bigger crowd they are shooting at.
OKW, UKF and soviets have flame tanks.
Ost has blob nuker(brummbar) and THE best off-map against blobs, the pin plane loiter.
Ostwind is so overpoweringly good it needed a limit of hitting 2 models maximum.
All factions have very effective blob countering tools.
Counter doesn't mean "1 click and everything is wiped".
