I'm not saying that it never suppresses (which it does equal to allied type MG's) I'm talking about pinning, which it never does at all.
It takes roughly half a second more to suppress than an HMG42 - as pinning certainly takes longer to have happen than suppressing and troops can manage to crawl into some cover to further slow it down while the Vickers is otherwise totally alike to an HMG42, its ability to pin is certainly compounded to be noticeably worse than an HMG42 (and I recall pinning makes troops easier to hit, so that might also be a consideration to comparing the two's DPS [heh, remember when pinning was just something that happened to people who forgot about the retreat button?]).
>35 is also where you have to start worrying about grenades, especially the rifle grenade which reach 30.
Indeed, the "advantage" is not without clear risks to make it more of a distinction than a clear advantage.
At least it's got "Best range ever while in buildings", eh?
