Unlikely. Unless I am very mistaken, MG42 has the exact same suppression value as in the last patch, meaning, if you run into it at short range&no cover, you will get suppressed on the first burst, otherwise, its gonna need at least 2. All it did receive, in practical terms, was a long range damage buff. Because the long range damage output was exactly its problem ...
The main problem with MG42 is the RNG of:
1)burst duration
2)cooldown between bursts
Sometimes, the MG starts firing, but because of RNGesus, it stops before if can suppress, if you are even more unlucky they take for ever to fire again. By that time, you either have a frag or a smoke grenade up your ass.
But, with the current changes, they are gonna vet faster. A vet 2 MG42 is a pain in the ass for the enemy.
