No one denies mg 42 beeing better than vickers. Its about fullfilling its intented role. If you want to buff vickers to mg42 level you would need to strip something off like bolster squads.
Or
Now hear me out...
OR have a unit.... Now here is where things get radical... Do the job its supposed to do.
I know it's nuts, an MG stopping even a lone squad, but if the brit wanted raw dps they would just grab another Tommie squad.
The job of the vickers is to stop massed infantry. It fails at that task. Full stop.
No "uuuuuhhhhg but bolster!!!!!"
It doesn't do its job.
By your logic the mg42 could have all the supression of an AT gun because "waaaaaaaaah bunkerzon grens!!" that's not how this works
A unit should preform its job properly and then be adjusted accordingly to faction flare, flavor and balance.
An MG SHOULD stop infantry frontally charging it, regardless of faction. The OST once can do it better, but all of them should do it at the very least.
