MG42s are fine. This patch just forces you to stop using Rifle Company as if it was meta. Pak howitzer, Mortar Halftrack, M8 Scott are all some of the hard counters for MG42s. Just l2p.
I dont really think that it's that big of a deal. It's just situational. It wont work that well on close range against AGrens or Shock Troops and it certainly wont win long-range against G43s. They work when they need to and they're not overpowered for the cost.
I wouldn't go as far as to remove it, it's just a nousance but not overpowered. If it was to be changed, atleast make the AOE a bit smaller or increase the time required for it to be dropped. I dont have a big problem with the ability.
