Yes blobbing is still effective and allies don't get the tools to easily counter until units like the Scott and kat show up. Brits I can't comment on.
That being said its easy to punish blobbing but its also wayyyy to potent more than it has any right to be and that is b/c the shear amount of CQC upgrades OKW blobs get. I can chuck nades all day long but when it comes down to brass tax blobbing is not punished enough in coh2 (same goes for USF blobbers).
I'm not rly sure how to fix besides make cover changes or make allied MGs simply have a higher AOE suppression than they do now
- Vicker's kills the model half the time and ROF and turn rate makes for an issue dealing with low health yet larger/wide blobs
- .50 cal suppresses but never pins
- Maxim small fire arc, cost, and long set-up time make it hard to pin a lager blob and requires the user to micro focus 1 unit but half the time you'll get flame naded out and get stuck in deathloop
