I liked how in CoH1 the Grens were good static with LMG but they were also very strong used aggressively on the move. CoH2 they are really good with the LMG and pretty lack luster on the move with Kar98s which makes spamming the LMGs a no-brainer. Making the rifles deadlier at CQB is the solution.
G43 make grens effective on the move and on close distance.
