brits stay in cover on vital points all the time, so do conscripts its one of their main assets, pls dont tell me how to play the game 
Yes, and you're not going to spot opposing defending force from your own defensive position without scouting unit or moving sections out of cover forward...
Why everyone is just comparing the costs ? It is literally hypocracy to say MGs are natural counters to blobs and "this clip" is fine.
In the clip they dont even have weapon upgrades and straight up frontrally engage MGs, which is not fun.
1 squad can crawl up to Maxim, its impotent at stopping anything, blobs obliterate it and it can't even suppress 2 LMG ober squads before they wipe it.
Vickers also got pretty low suppression, but at least it might kill a nade throwing model first, giving it a chance to suppress the squad.
.50 cal is pretty good, but extremely rarely used due to how faction plays.
HMG-34 is only slightly worse then 42, which is in line of its cost.
HMGs do counter blobs, but they don't do it alone. You're going to have to use spotter to fully benefit from HMGs range.
60 range TDs also don't exactly shine with vehicle up their face, so scouting is needed too.
