Actually it's harder, because in CoH2 literally all you do is walk up to the MG and kill the gunner no extra effort required.
How pointing a jump ability from outside of heavy bolter range right on top of them and hardcountering it this way is harder then walking up to MG?
And since you're talking about killing gunner and not actually throwing a nade, then let me remind you this again:
Only one faction got obersoldaten and their power level over 9000 will get reduced to normal human strength in 3 days.
