No need to, because and can't take 7th man with it anyway and all of the other possibilities, mainly LMGs make them weaker on the long run and you can't exactly share BARs, exceptions maybe being flamer or AT for the lulz.
A little short sighted maybe, but nothing we didnt expect
If they take your dropped LMG42 on their PPSH squad you can't have that 2 LMG grenadiers. Flamer on your PPSH-conscripts or the SVT drop (for team games) is really nice.
