In the early game when ever model loss counts towards setting the pace of the rest of the game, I find the Vickers very advantageous since it's capable of forcing mg42s off in a green vs green fight or structure vs structure
The vicker sniper model a bit better. Even assuming that's true it's still worst at suppressing than the mg42. It's better in certain situation but worst in other, so it should cost the same at best.
I think MGs are good as they are. Indeed they are different. Vickers have better damage, their vet+garrison range bonus is great. Sure they have less suppression than MG42, but no one said those two should be the same. So i think no change needed at all.
as best it's different, yet the vicker is more expensive. At least lower the price to 260 if the vicker is not actually superior.
If I'm paying 20 mp more for a hmg, I expect it to be better.
If 50 cal and vickers were to become as good at suppression as the mg42, you make it extremely difficult for okw to fight mgs. Unless you want to give volks grenadiers smoke nades that is.
the .50cal arrive much later than the other mg. The OKW can comfortably get a LeIG at around the same time as the USF get their .50cal.
The OKW have vastly better mobility over the british. It's basically the classic US vs Wehr scenario.
