The ISG got a buff vs blobs, and your mainline Volks will deal more damage at vet 5, But I do suspect we will se more doctrine infantry being used (since they are no longer outshines by Obers, and since the faster raketen will bring more AT to make up for the lower number of Volks)
Volks are not supposed to deal damage but hold the line,dealing damage should be the obers' job.
But now.....
